Q. If a body is accelerating:
A. It may speed up
B. It may speed down
C. It may move with same velocity
D. It may move with same speed
Options correct are:
(a) (A,D)
(b) (A,B,D)
(c) (B,C)
(d) (B,C,D)
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.
