If a constant torque is applied to a body that rotates without friction around a fixed axis, the changing angle of rotation increases proportionally to the square of the time and the angular velocity proportional to the time.
1.Measurement of the laws of angle and angular velocity according to time for an uniform rotation movement.
2.Measurement of the laws of angle and angular velocity according to time for an uniformly accelerated rotational movement.
3.Rotation angle; is proportional to the time t required for the rotation.
