Question

14)In a free fall the velocity of a stone is increasing equally
ion equal intervals of time under the effect of gravitational
force of the earth. Then what can you say about the
motion of this stone? Whether the stone is having:
(a) Uniform acceleration

(b) Non-uniform acceleration
(c) Retardation
(d) Constant speed
explain it also

Answer 1

(a) Uniform acceleration

Solution,

In a free fall, the velocity of a stone is increasing equally  in equal intervals of time under the effect of gravitational  force of the earth.

In the case of free fall, an object moves under the action of gravitational force. The only force that acts on it is force of gravity. The value of g is 10 or 9.8 m/s².

So, we can say that the stone is having uniform acceleration. Hence, the correct option is (a).
