Question

7. A body performing uniform circular motion in a horizontal plane has a constant
a) velocity
b) acceleration
c) kinetic energy
d) displacement
​

Answer 1

Answer:

The answer for this question is option (a) velocity.

When a body moves in a circular motion, its velocity remains constant, acceleration varies due to the change in its direction. Displacement here is zero as the body again comes back to its initial position i.e. the point where the body started to move.
