Give examples of these statements

b)A body having zero velocity may not have a zero acceleration.
c)A body having a varying velocity without having varying speed.
d)A body having a non zero acceleration without having varying speed.

Solution

(a) In case of uniform circular motion, the body moves with constant speed but it has an acceleration towards the centre of circular path.
(b) When a ball is thrown vertically upwards, then at the highest point it has zero velocity but non-zero acceleration (acceleration due to gravity).
(c) In case of uniform circular motion, the speed of body is constant but velocity is changing due to the change in direction.
(d) In case of uniform circular motion, the body moves with constant speed (i.e. without varying speed) but it has an acceleration towards the centre of circular path.

Explain your answer.

Mark the correct statement(s)
(1) If speed of a body is varying, its velocity must be varying and it must have non-zero acceleration.

(2) If velocity of a body is varying, its speed must be varying.

(3) A body moving with varying velocity may have constant speed.

(4) A body moving with varying speed may have constant velocity, if its direction of motion remains constant.
