A : The motion of body projected under the effect of gravity without air resistance is uniformly accelerated motion.
R : If a body is projected upward or downwards, then the distance of acceleration is downward

The acceleration of a body projected upwards with a certain velocity is

A : The relative acceleration of two objects moving under the effect of gravity, only is always zero, irrespective of direction of motion. R : The acceleration of object moving under the effect of gravity have acceleration always in downward direction and is independent from size and mass of object.
