The Pendulum . A mass hanging from a string or attached to a rigid rod i.e. a pendulum is another example of a system which exhibits periodic motion. In such a case the mass is known as a bob. The equilibrium position is when the string or rod hangs vertically. If the pendulum is not in this position there is a restoring force.

The Simple Pendulum. A simple pendulum is defined to have a point mass also known as the pendulum bob which is suspended from a string of length L with negligible mass Figure PageIndex1. Here the only forces acting on the bob are the force of gravity i.e. the weight of the bob and tension from the string.

• ### Pendulum Impact Force Calculation | Physics Forums

Oct 22 2009 Force is bad choice here because the force depend on the time the impact takes which can be very short indeed. You'd be much better off with momentum; you would want to calculate the momentum of the pendulum right before the impact and then apply conservation of momentum which does give you the subsequent motion of the impacted object under suitable constraints.
