Question

Can a body have a constant velocity but a varying speed? Give an example.

Answer 1

1. Speed is the measure of how much distance a body is covering per unit of time. It is a scalar quantity.
2. Velocity is known as the change of displacement as a function of time. It is a vector quantity.
3. Speed can also be defined as the magnitude of velocity over a period of time.
4. A body can have a constant speed but varying velocity like in the case of uniform circular motion but the opposite is not true.

Hence, No, a body cannot have a constant velocity but a varying speed.
