Question

speed of a body constant can can it accelerate
​

Answer 1

Explanation:

Yes, A body can have constant speed but still accelerate as in case of uniform circular motion. In uniform circular motion speed remains constant and direction of velocity changes with every point in the direction of tangent drawn from that point.

Answer 2

Answer:

Explanation:

Yes there can be a situation in which there is acceleration even when the particle is moving with constant speed.

For example in uniform circular motion (when there is constant speed) there is a acceleration towards the center known as centripetal acceleration .

If there was no centripetal acceleration it would have been impossible to rotate the particle in a circle.

But note that the velocity of the particle is not constant because the direction of the particle is changing continuously.
