Discuss the observation of Galileo for the objects falling freely.

What is free fall ? Write equations of uniformly accelerated motion for object falling freely.

Write the equation of acceleration which is used for height h ltlt R_e from the surface of earth.

When a ball A is thrown in vertically upward direction with velocity 20 ms^(-1), exactly at the same time another ball B is allowed to fall freely from height 1. The magnitude of velocity of A with respect to B at time 2 sec is ...... ms^(-1) (g = 10 m//s^(2) )

When an object is falling freely from the height h from the earth's surface its gravitational potential energy decreases gradually but its mechanical energy does not change.
