Force is that cause by which -
1. We can create motion in body.
2. we can stop a moving body.
3. We can change dimension , size or shape of the body.
WHEREAS
The free fall is known as acceleration due to gravity which is uniformly accelerated and is not effected by size , shape or mass of the body . It is same every body.

What is force ?
- Force is defined as a push or pull.
- It is calculated as :
Force = Mass × Acceleration.
- It is denoted by F.
- F = kg × ms^-2
- It's SI unit is kg ms^-2 or N ( Newton ).
- It can cause motion , stop motion, change shape and size of a body , change direction of motion , etc.
What is free fall ?
-When an object or body drops down from a certain height only and only under the influence of gravitational force is called a free fall.
- The acceleration attained by a body during a free fall is called acceleration due to gravity.
- The value of acceleration due to gravity is same for all objects or bodies on Earth . It's value is 9.81 m s^-2.
