Question

which phrases are the best examples of potential energy? for all questions, read the slides (in the instructions). exit ticket questions are highlighted with this color

□ a ball at its maximum height
□ a ball sitting on top of a hill
□ a ball resting at the bottom of a hill
□ a ball rolling on the ground

Explanation:

Potential energy is the energy stored in an object due to its position. A ball at its maximum height has gravitational potential energy because of its height above the ground. A ball sitting on top of a hill also has gravitational potential energy due to its elevated position. A ball resting at the bottom of a hill has no height - related potential energy (assuming the bottom is the reference level for height). A ball rolling on the ground has kinetic energy (energy of motion) rather than potential energy.

Answer:

a ball at its maximum height, a ball sitting on top of a hill
