Question

Is it possible a body having constant velocity but varying speed?

Answer 1

Answer : No, A body with constant velocity can not have varying speed.

Detailed explanation :

Speed is the distance covered by the object in unit time.

Velocity is the displacement covered by the object in unit time.

Here, Speed is a scalar and Velocity is a vector.

Vector has both magnitude and direction.

Speed has only magnitude.

If a body has constant velocity, then it's direction is constant along with the magnitude. If magnitude is constant, Then speed should be constant. :)

This proves, A body with constant velocity must have non varying speed
