State the series of changes in energy when a pole vaulter runs towards the bar and crosses it.

Expert Answer:

As the pole vaulter runs towards the bar, he gains kinetic energy. As he bends the pole, he does work on the pole and stores elastic potential energy in the pole. That energy is converted into gravitational potential energy as he goes up and over the bar.
