Vocabulary: potential energy, gravitational potential energy, elastic potential energy, kinetic energy
1. Read the article and answer the following questions.
a. What is potential energy?
b. Compare and contrast gravitational and elastic potential energy, and give an example of each.
c. The diver on the diving board in the opening picture weighs 500 Newtons. The diving board is 5 meters above the ground. What is the diver’s gravitational potential energy? (Gravitational potential energy (GPE) = weight × height)
