Text Solution

Verified by Experts

The motion of any object under the influence of the force of gravity alone is called as free fall. During free fall, there will be no change in the direction of motion of the object. But there will be a change in the magnitude of velocity of the object due to the gravitational pull of the earth . The acceleration that an object experiences during free fall is independent of the mass of the object undergoing motion. when a body is dropped freely from a height, its initial velocity is zero. Whereas when a body is thrown vertically upwards, its final velocity is zero .
