Question

acceleration of freely falling bodies is independent of mass

Answer 1

Thanks for asking the question.
When an object falls towards the Earth under gravity in the absence of air resistance, such an object is called free falling body.
All objects in free fall near earth have acceleration which is acceleration due to gravity.
For example, if a body is thrown in downward direction, the acceleration will be -9.8m/s/s. Negative sign is due to the direction of the ball which is vertically downward.
Free falling stones of different masses can prove that the acceleration of free falling body is independent of mass.
Hope it helps.
