Question

Can a body have constant speed but variable velocity?

Answer 1

Answer:

Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time.

Explanation:

One simple example is what we call Uniform Circular Motion (Uniform circular motion can be described as the motion of an object in a circle at a constant speed). For example, consider a vehicle moving with a constant speed on a circular path. Here, the speed is constant, but the direction of the vehicle is changing continuously. As we know, velocity is a vector quantity, so as the direction of motion changes, velocity also changes.
