Explanation:
I) Acceleration due to gravity is the acceleration that is gained by an object due to the gravitational force. Its SI unit is ms².It is a vector quantity.
ii) Consequently, the acceleration is a=Fm=GMR2, which is independent of the mass of the object. Hence any two objects that are subject only to the force of gravity will fall with the same acceleration and hence they will hit the ground at the same time.
