Question

In which motion, linear momentum changes but kinetic energy does not?

Answer 1

Hello friend !!!

Here's the answer you are looking for

In uniform circular motion linear momentum changes but kinetic energy does not.

This is because in circular motion, linear velocity keeps on changing at each and every point as it is a vector quantity.
Momentum or linear momentum is velocity dependent and thus it changes as velocity changes because it is a vector quantity as well.

But since kinetic energy is not a vector quantity it doesn't change in circular motion.

UNIFORM CIRCULAR MOTION, LINEAR MOMENTUM CHANGES BUT KINETIC ENERGY DOES NOT CHANGE.
