Answer:
• The falling of a body or object from a height towards the earth under gravitational force is called Free fall of body.
• The uniform acceleration produced in a freely falling body due to the gravitational force of earth is called acceleration due to gravity.
• The acceleration due to gravity,g = 9.8m/s square.
• When a body is dropped freely, it falls with an acceleration of 9.8m/s square.
• When a body is thrown vertically upwards, it undergoes a retardation of 9.8m/s square.
Explanation:
The answer is very easy.

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.
