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.

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 a straight line. Suppose at time t1 object is at point P moving with velocity v1 and at time t2 it … 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.

How to solve Simple Harmonic Motion(SHM) problems effectively for JEE Main/Advanced

What is Periodic Motion : In Physics, a motion that is regular and repeating is called Periodic Motion. The time to complete one full motion is called the Time period of the Periodic Motion
What is SHM: A Simple Harmonic Motion is a special case of Periodic motion where a physical quatity varies sinusoidally.In this Periodic motion the restoring force is directly proportional to the displacement. The object oscillates between two position and Motion is sinusoidally in nature.
