## 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

## What Are Free Body Diagrams

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.

## 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,

## Acceleration formula Explained with Examples

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 »

## How to Solve Equilibrium and Potential energy Questions Effectively for JEE Examination

What is Equilibrium

A rigid body is supposed to be in equilibrium if there is no change in translational motion and no change in rotational motion
The general conditions for equilibrium are as follows
(i) The total force must be zero
(ii) The total torque about any axis must be zero.
In many cases it is convenient to consider torques about axes through the centre of gravity.

Types of equilibrium
We can divide the equilibrium into two categories With respect to the state of a body
1. Static equilibrium.
2. Dynamic equilibrium.
