Answer :
The change in the angular velocity and number of revolutions is given as,
when the angular velocity decreases the number of revolutions also decreases.
The rotation rate, which refers to how quickly an item rotates or circles in relation to another point, is measured vectorially by angular velocity.
Angular velocity can be defined as the speed at which an item rotates or revolves around an axis. The Greek letter omega stands for angular velocity. The SI unit of angular velocity is radians per second because it is measured in angle per unit time.
The only distinction between revolution and rotation is that the axis of rotation in a revolution is located outside the body. Both motions of an item or body in space are circular.
