Question

What happens to speed ,velocity , acceleration when an object moves in a circle with uniform speed?

Answer 1

Objects moving in uniform circular motion will have a constant speed. ... The direction of the velocity vector is directed in the same direction that the object moves. Since an object is moving in a circle, its direction is continuously changing.

Answer 2

When an objects moves in a circular path:

 ⇒It has uniform speed

Uniform speed :
             " If an object covers equal distance in equal interval of times, we say that it is travelling with uniform speed "

⇒As direction of motion changes for every point in a circle , velocity of object also changes.

⇒As velocity is changing, we can the motion of the object is accelerated.
