In this article I would discuss what are free body diagrams and how to make one. Free body digrams are of immense importance when one want to study physics. You will find great deal of their usage while studying mechanics and tou can hey have equal inportance when it comes to other branches of physics. However i will discuss their usage and construction in context to mechanics.
Net Heat flow at a junction is Zero
Internal Energy does not depend on the path
Internal Energy in a cyclic Process is zero
Workdone is given by the area enclosed by the process on the PV diagram
Always make sure you Heat(Q) ,Internal Energy(U) and Work(W) with correct sign in equation
This mathematics sheet would be helpful for quick revision of most of maths formulas needed before class 11 and 12 physics examination. It covers quick and much needed formulas on differentiation , integration, trigonometry, AP, GP etc.
This tour is given to give the feel of the whole chapters plus the type of questions and ways to tackle them.This is quite beneficial for anybody studying One dimensional Motion.
One dimensional Motion is the study of the motion along an straight line.Complete Study material has been provided at the below link
We often comes across the problems in mechanics where we need to apply the law of conservation of energy where gravitational potential energy or gravity is involved . For solving such problems you can consider the following problem solving strategy,
Acceleration Formula Acceleration is the rate of change of velocity with time.It is a measure of the change in the velocity of an object per unit time and mathematically acceleration formula is given as For describing average acceleration, we first consider the motion of an object along straight line. Suppose at time t1 object is at point P moving with velocity v1 and at time t2 it is at … Continue reading Acceleration formula Explained with Examples
1) Read the instruction of the paper and see if there is any negative marking. This will help you in making educated guess.There are two types of Multiple choice questions. a) Only one answer b) can be more than one. Always check the instruction before attempting the question
2) Take a brief tour of the paper,so that you have a idea of the whole paper. Start your paper with Easy question.
3) Read the question before you look at the answer. Come up with the answer in your head before looking at the possible answers, this way the choices given on the test won’t throw you off or trick you.
4) Cross out any answers that you know are wrong.
5) Always Read all
Students deal with lots of stress during the examination days. We can reduce the stress and stay calm and get success by following these simple steps
1)Take practice tests. The single best way to prepare is to practice. Taking sample exams under similar conditions as the real one will familiarize you and increase your confidence Level. This should be done few days before the examination days. The day before examination should be kept for revising the notes only
