This unit is designed to study the characteristics of centrifugal force. Whenever a body rotates, it experiences centrifugal force. This force tends to push the body out of the circle. Its magnitude is directly proportional to mass and velocity of the object while it is inversely proportional to the radius of the circle in which the body rotates. The unit consists of a small metallic rod on which the mass is placed.

The rod is placed in a guided path by means of two grooves. It can be rotated at any speed with a control panel that controls the rotational speed of the rod. The force acting on rod due to the mass attached to it is displayed on control panel by force indicator.

The unit enables the forces exerted on rotating masses to be studied. The core of the unit is a rotating arm with a vertical axis of rotation. Mass bodies made of metal are anchored to the arm in retaining holes. The centrifugal force exerted is transmitted from the arm to a bending bar. The deformation of the bar, which is proportional to the force, is recorded by an electronic measuring system and is displayed digitally. The rotational speed of the regulated drive motor, also displayed digitally, can be continuously adjusted using a 10-turn potentiometer. In operation a transparent protective lid covers all rotating parts but nevertheless ensures a clear view of the experiment. The table unit can be set up where required and does need to be clamped in place, the unit is also portable.
