MCQ

Check up the only correct statement in the following :-

A
A body has a constant velocity and still it can have a varying speed.
✓
A body has a constant speed but it can have a varying velocity.
C
A body having constant speed cannot have any acceleration.
D
A body in motion under a force acting upon it must always have work done upon it.

✓

Answer

Correct option: B.

A body has a constant speed but it can have a varying velocity.

b
When a body possesses constant velocity, both its magnitude (i.e., seed) and direction must remain constant. On the other hand, if the speed of a body is constant, then its velocity may or may not remain constant. For example, in uniform circular motion, through the speed of a body remains constant, velocity changes from point to point due to a change in direction. A body moving with a constant speed along a circular path constantly experiences a centripetal acceleration.
