Demonstrate the relationship between angular velocity and centripetal acceleration. The low cost and simple construction of the centripetal force apparatus make it a must for every classroom. The experiment uses the weight of 20 washers hanging from one end of a nylon thread to balance the pull of a rubber stopper swinging overhead. Complete instructions provided.
