Question

what is acceleration of free fall​

Answer 1

A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). This numerical value for the acceleration of a free-falling object is such an important value that it is given a special name. It is known as the acceleration of gravity - the acceleration for any object moving under the sole influence of gravity. A matter of fact, this quantity known as the acceleration of gravity is such an important quantity that physicists have a special symbol to denote it - the symbol g. The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.

Answer 2

Answer:

An object that is moving only because of the action of gravity is said to be free falling and its motion is described by Newton's second law of motion. ... The acceleration is constant and equal to the gravitational acceleration g which is 9.8 meters per square second at sea level on the Earth.
