Principle

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.

Benefits

Long runtime
Nearly friction-less movement due to precision bearing
Steady set-up prevents interferences
Data logging reveals instantaneous results during measurement

Tasks

Measurement of the laws of angle and angular velocity according to time for a uniform rotation movement.
Measurement of the laws of angle and angular velocity according to time for a uniformly accelerated rotational movement.
Rotation angle; is proportional to the time t required for the rotation.

Learning objectives
