## Conservative and Non conservative forces

Some Points about Conservative forces and Non conservative forces
1) Potential energy are defined for Conservative forces
2) An object that starts at a given point and return to the same point,then
net workdone by the conservative force is zero while in case of non conservative force ,it will not be zero

## Thermodynamics Problem solving tips

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

## How to apply law of conservation of energy in mechanics

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,

## Techniques for multiple choice questions for Examination

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.
