8th Grade Science MAP Review

One bar magnet sits on a table, and a rubber band suspends another magnet above it. In the view on the left, the upper magnet is held in place and cannot move. In the view on the right, the upper magnet has been released. How did the potential energy change when the upper magnet was released?

• Magnetic, elastic and gravitational potential energy increased.

• Magnetic, elastic and gravitational potential energy decreased.

• Magnetic and elastic potential energy increased, and gravitational potential energy decreased.

• Magnetic and gravitational potential energy decreased, and elastic potential energy increased.
