1.

can a body have uniform speed and variable velocity simultaneously?

Answer»

Yes, it can have but only in the case of uniform circular motion.

Explanation:

In uniform circular motion through a body moves with a constant speed its direction keeps on changing(along the tangent drawn) as it is a circular path, hence the velocity also keeps on changing(velocity is a vector quantity that means it depends on direction) and therefore we can say that a body moving in a uniform circular motion has uniform speed as well as variable velocity at the same time.

(uniform circular motion means a circular motion with constant speed)
