Back to school survival guide for parents Part 1

Back to school survival guide for parents Part 1 Back to school survival guide for parents Part 1: Readjusting to academic life Going back to school can be just as hard on parents as it is for kids. Some parents are sad to see their little ones go off to school for the day while others are happy they have a bit of time to get things done at home or work. Once school starts, kids will come home with varying levels of homework depending on their age, lots of stories to tell, and perhaps a little bit of stress. Academic life involves more than just getting assignments done; rather its a whole new set of things for parents to manage. Whether their kids need help with homework, communicating with the teacher, or socialization parents have a big job ahead of them while their kids get readjusted back to their academic lifestyle start the school year off right with the help of private Orange County academic tutoring from TutorNerds. 1.   Homework (a lot of homework) One of the biggest complaints parents have in general is that their children have too much homework. They seem to be getting more homework at an earlier age, which leaves less time for families and relaxation after school. It can be difficult to manage this amount of homework, but there are some strategies that are helpful. For instance, students can learn to cut out a fair amount of busy work and study more efficiently. They can also look at setting up a schedule, so they dont get too far behind on compounded assignments such as chapter reading. The more time a child has to get exercise or just rest after school, the more likely they are to be productive overall. 2.   Readjusting to a daily schedule Adjusting back to a daily school schedule takes a little bit of time. Usually, after the first-month kids are used to getting up at a certain time and concentrating during school hours. However, as kids grow, they may need to make minor adjustments in their schedule, so they have time to work on difficult homework assignments or just have a mental break from academics. In many cases, experimenting with different options is the best way to establish a productive routine, especially for older kids in middle or high school. 3.   Socialization Socialization is a big part of being at school, especially if a student is moving up to the first year of middle school. Some kids are social butterflies while others are on the shy side. Either way, its important to chat with kids about their new friends and look out for any instances of bullying. Life in the classroom can be a lot easier if kids have friends who are good role models and who practice kindness. 4.   Stress management These days, stress management is an issue even for younger students. Some of the most common things that cause excess stress include lack of sleep, too much time sitting at a computer, lack of exercise, or not enough down time. If kids have difficulty managing stress they might also need academic help from an in-home tutor or need to talk with their teacher after class to get some study tips. 5. Down time One of the biggest things that kids can do to transition back to the school year is just to get some relaxation time. Perhaps theyre reading their favorite ‘just for fun’ series of novels or maybe they’re hanging out in the backyard with the family pet. Parents also need some down time as they help their kids transition back to school. One of the biggest transitions occurs when students start middle school. There will be a lot more homework at a time when their brains are growing, and emotional levels are high. However, downtime usually helps the adjustment back to the academic From foreign languages to math, our private Orange County tutors have you covered. Call us today for more information.

Smartest Answers to Nine Common Interview Questions

Smartest Answers to Nine Common Interview Questions Image via Unsplash.com Question: “What can you bring to our company that nobody else can?” This question encompasses the equally common question of “why should I hire you?” You’ll want to think hard prior to interview day about what exactly differentiates you from other candidates. Of course, everybody is different (and everyone knows this), but for this question, you’ll want to be specific: when you envision yourself in the role, what are your strengths? What assets have you already developed elsewhere that you can apply in this position to improve the company at large? If you communicate to an employer that you can solve a problem for them (and not create more problems for them), you’ll stand out. The smartest answer for this common interview question is the answer that best displays your uniqueness and expertise, perfectly aligning you with the position you are seeking. Question: “Where do you see yourself in 2 years? 5 years? How can this job help you get there?” This is an overwhelming question for most of us, and it can leave you stumped in the interview room. You may also encounter it this way: “How do you see this position advancing your career?” Best way to answer it? Break it down, and think small before you scale your plans larger and larger. What do you want to have accomplished professionally, academically, personally in 6 months? One year? Would you like to learn Adobe InDesign to strengthen your graphic design portfolio? Do you want to have landed a paid internship at a nonprofit? These are great shorter-term goals that can figure into a more long-term plan that suffices as an answer to this common interview question. Perhaps your 5-year plan includes more networking, launching a website, and building connections to fuel your career. A question like this can throw you off only if you’ve never considered your professional life in a greater context, and if you have any interest in the job for which you are interviewing, you should be able to explain how it fits into your greater goals pretty easily. If you can’t easily see how this job will advance your career, perhaps it isn’t quite the right job for you. Infographic by Julia Dunn Question: “What motivates you?” This is an opportunity to get a bit personal or vulnerable. You might even bring up a more personal story of struggling through a tough time; for many, motivation comes from a desire to help support one’s family, avoid poverty, and so on. Of course, you don’t want to divulge too much personal material if it isn’t appropriate, but you can usually connect motivation to any experience you’ve had that was pivotal to you gaining clarity about your career path. Perhaps you’re interviewing to become a preschool teacher; you can instantly contextualize “motivation” if you consider it relative to your career aspirations. What motivates you to serve as an excellent role model for young kids? What keeps you going when things go awry? How did you gain clarity to know you wanted to work with toddlers? It’s hard to think about motivation when it’s nebulous and de-contextualized, so if you’re stuck during an interview, re-frame the question in your mind: “what motivates you [to succeed in marketing? to be a great speech-language pathologist? to work with marginalized communities?]” You’ll be able to answer the question more quickly. Question: “What would you need from me to be successful in this role?” This is one question not to take lightlyâ€"here, you are granted the perfect time to establish your own expectations for your employer. Remember that interviews are not unidirectional; while being interviewed yourself, you are also interviewing the employer to see if they’re a solid match for you. The best answer to this question is the honest answerâ€"as someone who values efficiency, communication, and timeliness in the workplace, I would say something like “to be successful, I would hope that my employer isn’t afraid to give me both positive and constructive feedback, delivers assignments to me clearly and quickly, and communicates with me regularly.” Tell your employer what they can do to help youâ€"it’s not a trick question! Many of the happiest employees in any workforce are those who have conscious, receptive employers and supervisors who truly invest energy in supporting employee needs. If, when asked this question, you don’t disclose exactly what you need from an employer, you risk running into a situation you could’ve prevented had you been transparent about your values. Question: “Do you prefer teamwork or individual work? Tell me about a time when you successfully navigated either type of work.” The smart way to answer this common interview question is not to choose just one or the other. The best answer, in my opinion, is something like the following: “I enjoy both types of work, but at different times. Sometimes a certain task, like filing, calls more for individual work and another, such as brainstorming ideas for a new company project, may benefit from a team of people. You have to have awareness about when to do a task alone versus when to collaborate, because if you use teamwork on a task that’s more suited for work alone, you risk lowering efficiency and wasting time.” Question: “How do you manage teamwork? Are you a leader or follower?” This question might follow the previous one, or be combined with the above question. Teamwork is often a necessity in the workplace for most jobs. If you aren’t working with a large team, you may be interfacing with at least one or two other colleagues at work. To answer this question, reflect on moments in your professional life where teamwork was successful or unsuccessful, and explain why. At the same time, convey the role you assumed as part of a team: do you usually take initiative to lead the group and delegate tasks? Or, do you prefer to “follow” and wait for someone else to take charge before you? Understanding your own working style is crucial to successfully answer this common interview question. Tip: Before your interview, make yourself a flowchart or document that aggregates your most useful past experiences. On the side of each memory description, indicate what each experience demonstrates about you (communication skills, organizational skills, exceptional teamwork, conflict resolution?) It really helps to have a list of stories in mind so you can jog your memory before coming into the interview. Question: “Describe how you would handle a high-pressure situation at work.” Employers are always interested in knowing how a potential employer handles stressful situations. How do you manage tight deadlines? A store full of customers in a frenzy for the next semi-annual sale? 3 tables of frustrated restaurant guests whose orders have been mixed up? Draw upon your own memories if you can; most of us can recall a work situation that went substantially wrong. How would you de-escalate an argument in the office? You get major bonus points as an applicant if you demonstrate masterful conflict resolution skills. Image via Unsplash.com Question: “Can you explain to me your understanding of what our company does? What is our mission statement and how do you see your role playing into this mission statement?” This is a common interview question that employers use to weed out the applicants who don’t truly understand the position, haven’t researched the company enough, or can’t situate themselves within the scope of work. You can best answer this question by taking plenty of time to read through the company’s website and other materials to acquire a strong understanding of the company before applying. “Study” as much as you can. Employers will take notice if you demonstrate a high level of understanding with respect to the company goals. This question is also an opportunity to explain why this mission statement resonates with you personallyâ€"why you share the organization’s values. You have a greater chance of getting the job if you make a strong argument for why you belong with the team (do well, and the interviewer might even feel like you’ve been on staff already for months!) Being knowledgeable and thorough in your company knowledge is crucial to interview success. Question: “Do you have any questions?” Yes. Always have questions! Saying “no” is the fast track to not being offered the job. Most thoughtful job applicants will have questions because they’ve analyzed the position details in-depth and engaged with the employer. Some great questions to ask if you’re stumped: “How long have you been with (company name)? What do you enjoy most about your job?” “What is this company’s largest challenge and how can I help overcome it?” “In what direction is this company/agency/organization moving? How has it changed in the last few years?” It’s best not to only ask about logistical matters, but to ask at least one clearly thoughtful question. Don’t just ask “how many hours can I expect to work each week?” Or “which holidays do we have off?” Asking a more macroscopic question about the company will both impress your interviewer and heighten your understanding of the organization. You’ve probably heard people say that job interviews go both ways: you are interviewing the employer just as much as they’re interviewing you. As an applicant, you are also responsible for deciding whether you’re a good fit for the job. Thus, you’ll want to do as much information-gathering as you can, and seek out opportunities to learn. Let’s try it again: You arrive at another job interview, spiffed up in a pencil skirt, perfectly-tailored blazer, and one of those collared shirts from Express that blends cuteness with professional attire just perfectly. The front desk receptionist welcomes your arrival and asks you to sit in the lobby while your interviewer prepares to bring you into their office. You sit eagerly in a chair by the tall indoor plant and flip through your notebook, briefly glancing at your “experiences flowchart” to refresh your memory of all you have accomplished and learned. You smile at yourself and recite affirmations in your head: I am prepared. I know what I’m doing. I’m qualified and ready to prove it. I have the experience I need. I am excited and capable of doing great work. The receptionist cheerfully gestures for you to stand up and walk over to the interviewer, who holds a copy of your cover letter and resume and ushers you into the conference room. You enter with confidence, grace, and all the knowledge you need to conquer your interview, no matter how funky those questions get.

Motion

Motion Motion Motion or movement is a topic and a concept which we experience every moment! There is not a second that we can claim that an object is not moving. It is fascinating to understand everything in the Universe is moving. But how? If we are sitting in our room by ourselves, we say that we are just sitting and not moving. But it should be noted that the person sitting in the room is simply sitting with respect to his roommate. But how about with respect to Moon? It may sound overwhelming, but yes because we are on Earth and Earth is continuously spinning around its own axis and around the axis of the Sun, if there is a person standing on the Moon, he will say that the person sitting in the room is also moving. So with the above example it is to be understood that the terms moving and not moving are relative terms, dependent on the surroundings. Whether we look at an apple falling from a tree, or the chemical and nuclear reactions, or the case of heart pumping blood, everything is moving and this change in position is termed as Motion. What is Motion? Motion is the change in an objects position with respect to its surroundings. Motion is also defined as the process of any movement or the action of being moved. The study of motion plays a huge and a very important role in Physics. The concepts of Physics always revolve around the aspect of motion. In Physics, the study of the motion of objects is termed as Mechanics. The branch of Mechanics which involves describing the motion of objects using various tools such as equations, diagrams and graphs is known as Kinematics. This motion is usually described in terms of distance, time, displacement, velocity and acceleration. Distance and Displacement: Distance is the physical quantity which describes how much path or ground an object has entirely covered during its motion. Distance is a scalar quantity as it only has magnitude and no direction. Displacement is the physical quantity which describes the objects overall change in position. It is also defined as the shortest distance of an object from its initial position to its final position. In many cases it is typically distinct from the objects actual path covered. Displacement is a vector quantity as it has both magnitude and direction. Let us look at an example below which tells us the difference between distance and displacement. Let a car starting at point P travel 3m down South and then 4m in the East direction as shown in the figure on the right. The cars initial position is at point P and its final position is at point B. The total distance travelled by the car = PA + PB = 3m + 4m = 5m However, the displacement of the car must be the shortest distance from the initial point to the final point, and this implies displacement = PB We can calculate PB by using Pythagorean Theorem == PB = (32 + 42) = 25 = 5m Hence the displacement of the same car is 5m. Speed and Velocity: The term used for describing how fast an object is moving is Speed. Speed is a scalar quantity as it is associated only with the magnitude. An object travelling faster has greater speed, and hence covers more distance in less amount of time. Velocity is a physical quantity which describes the rate at which an object changes its position from one point to another. Velocity is a vector quantity as magnitude and direction both apply to it. Acceleration: Acceleration is defined as the rate at which an object changes its velocity. This implies that an object is said to be accelerating only if it is changing its velocity. If the object is not changing its velocity and instead travels with a uniform velocity, then the acceleration of that object is said to be 0. If an object has an initial velocity of u and final velocity of v, then the average acceleration of that object in a certain time interval of t can be calculated using the formula shown below: Types of motion: There are 2 types of motion based on whether an object covers equal distances or unequal distance in a certain interval of time. a) Uniform motion: If an object covers equal amount of distances in equal intervals of time (it is alright if the time intervals are really short), then such a motion is known as the Uniform motion. Example: If a car covers 5m in the 1 second, 10m in 2 seconds, 15m in 3 seconds, then we say that the car is travelling with uniform motion as it is covering constant 5m in every single second. b) Non-Uniform Motion: If an object covers unequal amount of distances in equal intervals of time, or if it covers equal amount of distances in unequal intervals of time, then such a motion is known as the Non-uniform motion. Example: If a car initially travels 5m in the first second and then 12m in 2 seconds, and 18m in 3 seconds, and so on then it is non-uniform motion. Motion is primarily classified into 3 types based on the path taken by the object in motion: 1) Translatory motion: If the position of an object changes with respect to a fixed point (or object), without a change in its orientation, then such a motion is known as the Translatory motion. Theoretically the path of an object in pure translatory motion can be a linear path or a curved path. The motion along a straight line path is known as the linear motion and the motion along a curved path is known as the curvilinear motion. Examples: A bus moving on the road, path of a moving vehicle on a straight road. 2) Rotatory motion: If an object moves in a circular path about a fixed point in space (about the axis of rotation) is known as the Rotatory motion. Examples: The wheel of any moving vehicle, hands of a clock, spinning top etc. 3) Oscillatory motion: The to and fro motion of an object is known as the Oscillatory motion. Examples: Swinging pendulum, swings in a playground, swinging cradle etc. There are other types of motion such as vibrational motion, periodic motion, random motion which can also be observed in our daily life. Newtons Laws of Motion: Isaac Newton, a scientist in the 17th century put forward 3 laws that explain why the objects move and why they dont move. These 3 laws have been popularly known as the Newtons Laws of Motion. These laws are extremely important and are the baseline for various concepts in physics. 1)Newtons First Law of Motion: The first law states that an object at rest stays in rest and an object in motion continues to stay in motion (with the same speed in the same direction), unless acted upon by an unbalanced force. This law brings out an underlying concept known as the Inertia. Inertia can be defined as the tendency of an object to resist a change in its motion. Example: A coffee placed inside a car remains steady even when the car is moving forward. But in a situation when a sudden brake is applied, as the coffee continues going forward with the same speed in the same direction, it is spilled all over the wind shield. 2)Newtons Second Law of Motion: The second law states that the acceleration of an object as produced by a net force is inversely proportional to the mass of the object, and is directly proportional to the magnitude of the net force (direction being the same as the net force). This law when translated to a mathematical statement can be written as shown below: The above equation when rearranged gives us: 3)Newtons Third Law of Motion: When objects come in contact with each other, as a result of those interactions the push or pull that acts upon the objects is termed as Force. There are forces which are termed as Contact Forces as they result from interactions that come through contact. Examples of contact forces are normal force, tension force, frictional force, and any applied forces. There are other types of forces that show effect even from a distance. Examples of such forces are gravitational force, magnetic force, electrical force etc. According to Newton, whenever objects interact with each other they apply force on each other. And in this interaction the 2 forces that act upon the objects in contact, are the action-reaction forces. So Newtons third law states that, every action has an equal and opposite reaction. So this law clearly explains that forces always come in pairs, and when the objects are in contact with each other the size of forces (magnitude) on the first object by the second, and on the second object by the first are the same. The direction of force exerted on the first object is opposite to the direction of force exerted on the second object. Example: When a person sits on the chair, the person exerts downward force on the chair and the chair exerts upward force on the person. This is an action-reaction pair resulting from the contact between the person and the chair. Equations of Motion: There are 3 equations of motion which are used to describe motion of any object. These equations are in terms of distance, time, displacement, velocity and acceleration. 1)First Equation of Motion: Consider an object travelling on a straight line with an initial velocity of u at t = 0, and reaches final velocity in a certain time interval of t. If the acceleration during this time interval is a, then the first equation of motion is given as: Acceleration, a = Change in velocity/ Time a = (v u) / t This can also be written as == a * t = (v u) The above when rearranged gives us: v = u + a*t Example: A car initially starts at rest and when time is 6 seconds it travels with a velocity of 30m/s. What is the acceleration of the car in this time interval? Given: Car starts at rest == at t = 0, initial velocity, u = 0m/s After t = 6 seconds, final velocity, v = 30m/s Acceleration, a = ? From the first equation of motion we have: v = u + at This implies: 30 = 0 + a*6 == 30 = 6a == a = 30/6 = 5m/s2 Therefore, the acceleration of the car is 5m/s2 in the given time interval. 2)Second Equation of Motion: Let u = initial velocity of an object v = final velocity of an object t = total time taken for the object to travel a displacement = d a = acceleration of the object We know that: Average Velocity = Total displacement covered / Total time taken Now, Average Velocity can be written as the average of the initial velocity and the final velocity of an object. Therefore, average velocity = (u + v)/2. Substituting this average velocity in the above equation we get: (u + v)/2 = Total displacement covered / Total time taken ==(u + v)/2 = d/t. This gives: (u + v) = 2d/t Now from the First Equation of Motion we have: v = u + at. Substituting this into the above equation we get: (u + u + at) = 2d/t == 2u + at = 2d/t == t * (2u + at) = 2d == 2ut + at2 = 2d Now solving for d, we get: d = 1/2 * (2ut + at2) == d = ut + *at2 Example: Andrew is waiting at a stoplight. When the stoplight turns to green, Andrew accelerated from rest at a rate of 8.00 m/s2 for a time of 4 seconds. What is the displacement of Andrews car during this time period? Given: Initial velocity of the car, u = 0m/s Acceleration, a = 8m/s2 Time taken, t = 4seconds Displacement, d = ? From the given information, here we can use the Second Equation of Motion. Therefore, d = ut + * at2 == d = (0* 4) + (1/2 * 8 * 42) == d = 64m Hence the displacement of Andrews car during the given time period is 64m 3)Third Equation of Motion: Let u = initial velocity of an object v = final velocity of an object t = total time taken for the object to travel a displacement = d a = acceleration of the object From the First Equation of Motion we have: v = u + at. This equation when rearranged gives us (v- u) = at Equation 1 Now, we know that: Average Velocity = Total displacement covered / Total time taken (u + v)/2 = d/t. Hence (v + u) = 2d/ t Equation 2 Now multiplying both Equation 1 and Equation 2 we get: (v u) (v + u) = at * 2d/t Therefore we get: (v2 u2) = 2ad Example: Edward is driving a bike and he accelerates from 4m/s to a speed of 10m/s over a distance of 20m. What is the acceleration of the bike? Given: Initial velocity, u = 4m/s Final velocity, v = 10m/s Distance covered, d = 20m Acceleration, a = ? From the given information, here we can use the Third Equation of Motion. Therefore, v2 u2 = 2ad == (102 42) = 2* a* 20 == (100 16) = 40 * a == 84 = 40 * a Now solving for a we get: a = 84/40 == a = 2.1m/s2
