(a) Is it possible to be accelerating if you are travelling at constant speed?
(b) Is it possible to move on a curved path with zero acceleration, constant acceleration, variable acceleration

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
(a) On a curvilinear path (a path which is not straight
line), even if speed is constant, velocity will change
due to change in direction.
`:. a!=0`
(b) (i) On a curved path velocity will definitely
change (at least due to change in direction).
`:. a!=0`
(ii) In projectile motion, path is curved, but acceleration is constant (=g).
(iii) Variable acceleration on curved path is
definitely possible.
