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 total energy is all kinetic energy. As it rolls uphill to point 5, its kinetic energy begins to transform into all potential energy.
