A rubber band is stretched to its maximum extent. Analyze and explain the type of energy it possesses.

• The rubber band possesses kinetic energy because it is in motion

• The rubber band possesses potential energy because it has the potential to do work when released.

Analyze the energy transformation in a swinging pendulum and justify why the potential energy is at its greatest at a certain point.

• The potential energy is greatest at the midpoint of the swing because the pendulum is at its average height.

• The potential energy is greatest at the highest point of the swing because the pendulum is furthest from the ground, and potential energy is directly related to height.

• The potential energy is greatest at the end points of the swing because the pendulum is at rest.

• The potential energy is greatest at the lowest point of the swing because the pendulum is moving at its fastest.
