The movement of an object only due to its gravity is called a free fall.
The movement of the free-falling body can be studied using Newton's second law.
Newton's second law says that the force is obtained by multiplying acceleration and the mass.
The acceleration experienced by a freely falling body due to the gravitational effect of the earth alone is known as free-fall acceleration. It's also known as gravitational acceleration.
On Earth, it has a value of
The acceleration of a body falling freely in a vacuum at the earth's surface in the gravitational field of the earth: the standard value is 9.806 65 meters per second per second (32.174 feet per second per second).
