Abstract

The reduction of velocity in the free rocking motion of a rigid body on a rigid base has been hitherto explained on the basis of constant angular momentum. According to this theory, an abrupt reduction of velocity, in other words energy of motion, is justifiable, when the rigid body falls down on the base, even in the ideal case neglecting energy consumption.<br>This paper reports observations and considerations on the free rocking of the graphite prisms on various bases, and it has been clarified that the application of the law of constant angular momentum is not suitable and the reduction of energy must be explained by sliding, elasticity, sound or others.
