They both are related to each other.
Gravity is the force of attraction that pulls two objects toward each other.
A free falling object is when the object is falling due to gravity without air resistance. It also fall down at the same rate of acceleration ( 9.8
Free falling have two characteristics:
- it mustn't encounter any air resistance
- the only force that is acting upon an object is GRAVITY
- it also have the same rate of acceleration
I hope that will help you. x
