【 摘 要 】

A special apparatus has been designed to study linear, circular, and rotational motions. Thisapparatus consists of a flywheel, rotating in horizontal plane by the mean of a hanging mass. Thisflywheel carries a hole, which can be moved on a radial rail. This hole can be fixed at desired distancefrom the flywheel axis. Putting a metallic sphere on this hole gives centripetal motion with certainradius to this sphere. The moving hole acts by normal force on the metallic sphere and moves it incircular path. The increasing angular velocity of the metallic sphere has its maximum value when thesphere leaves the hole. Theoretical and experimental analysis for this apparatus shows that thecentripetal acceleration depends only on the geometry of both sphere and hole. The designed apparatushas a very simple design and does not have any undesired forces.
