The diagram shows a marble that is being released from rest at point 1. It is rolling down a ramp to point 7. Describe the energy of the marble at point 3 and as it rolls up to point 5.
At point 3, the marble’s mechanical energy is almost all kinetic energy and very little potential energy. As it rolls uphill to point 5, its kinetic energy begins to transform into potential energy.

Write a scientific explanation to describe the energy changes that occur while the pendulum is in motion.
The pendulum has the greatest amount of potential energy at its highest point, and as the pendulum moves down the potential energy is transferred into kinetic.
