Question

explain how it is possible for an object to move with a constant speed but with uniform acceleration

Answer 1

Acceleration is a vector quantity,so in case of uniform circular motion speed is constant but body is accelerating due to change in its direction

Answer 2

If an object is moving in a circular motion with a constant speed, there is always an acceleration acting on the object towards the centre. It's speed may be constant in this case but an acceleration is acting to keep it in the circle.
