## 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.

## Mathematics revision sheet for class 11 and class 12 physics

## Fictitous Force and Free falling Elevator

A non inertial Frame of Refrence is the frame of refrence which is having acceleration a. Example Free Falling elevator
Newtons law are valid in inertial frame of refrence only. We cannot apply them as it is in non inertial frame of refrence as it left out the acceleration of the object because of the frame of refrence.
Let me provide simple example to illustrate this.
