The HFC21 centrifugal force apparatus is teaching equipment used to perform experiments that enables the study of the behavior of centrifugal force. It simplifies the demonstration of the effect of mass, speed, and radius of gyration on the centrifugal force on a rotating mass. It houses a speed-controlled motor, a boom that rotates and onto which sliding weights are fitted and adjusted. The speed, mass, and radius of gyration can be set and centrifugal force can be measured through digital display. It is supplied six masses and with all the tools, spares, accessories, and an instruction manual necessary for the operation and performing experiments. The equipment enables students to experimentally verify results with theoretically measured values.
