1429 Rotational dynamics

Our apparatus consists of a variable binary gauge: the distance between the two sides of the binary gauge can be varied at its centre by means of a screw activated by an external knob.
The binary gauge is made of iron to prevent the ball’s weight (a billiard ball) from deforming the system’s geometry and affecting the results. A base to be positioned on the binary gauge and a level ensure the perfect horizontal position of the binary gauge. During the motion, the kinetic energy continuously transforms into rotational kinetic energy, creating curious effects, which can be explained with a detailed analysis of the centre of gravity position.
