Question

Is it possible for a body to have acceleration when moving with
(a) constant speed (b) constant velocity? Explain.​

Answer 1

Answer:

The velocity vector is constant in magnitude but changing in direction. ... For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing.

Answer 2

Explanation:

Yes,

a body can have a constant speed and still be accelerating. Acceleration can be either due to change in speed or due to direction of motion or both. Consider an example of a uniform circular motion. In a circular motion, the body moves with a constant speed but we still say that it is accelerating due to the change in direction

This acceleration is called centripetal acceleration and is given as

ac=v²/r

where v= constant speed

and r= radius of circle
