Pendulum

$pendulum.gif$

Consider the pendulum in the figure. Release it. When the pendulum hits the shoe, it will push the shoe forward, exerting a force on the shoe over a distance. if we were to multiply the force exerted on the shoe by the distance the shoe moves, we could calculate the amount of work that is done.

The pendulum had the ability to do work on the shoe because when the pendulum was at the raised position it had what type of energy?

Kinetic energy

Static energy

Gravitational potential energy
