CONSERVATION OF ENERGY:
= Constant (1)
Moment of momentum about the axis of the pole:
CONSERVATION OF MOMENT OF MOMENTUM:
= Constant (2)
Equations (1) and (2) describe the entire motion of the swingball. Initial conditions determine the values of the two constants. The equations need to be solved numerically.
