Question

Name the quantity that remains constant and changes in a uniform circular motion. Can the direction of a body change ,when acceleration is constant .If yes, how?

Answer 1

Answer:

Explanation:

During motion along a circle, velocity always changes as its direction always changes. But the magnitude of velocity, which is speed, may remain constant. In a circular motion, the direction of centripetal acceleration keeps changing, since it is directed towards the centre of the circle.
