Question

In uniform circular motion
(a) both velocity and acceleration are constant
(b) acceleration and speed are constant but
velocity changes
(c) both acceleration and velocity change
(d) both acceleration and speed are constant

Answer 1

Answer:

c)both velocity and acceleration change constantly

Explanation:

During uniform circular motion, the magnitudes of acceleration as well as the velocity remain constant but they change their direction at every instant. Hence only speed of the object is constant in uniform circular motion.

Answer 2

Answer:

here both acceleration and velocity always change
