Forms of energy in an apple: -As it grows: Chemical energy stored in the bonds of the molecules in the apple; Gravitational potential energy due to its position on the tree; -As it falls: Stored chemical in the molecules of the apple, kinetic energy due to the motion of falling; -As it is digested: Chemical energy in the apple is transferred to chemical energy in the bonds in molecules in the person eating it as well as energy in ATP used to drive the person's muscles.

Work Step by Step

This question asks you to think about different kinds of energy. The chemical energy is the more obvious, based on the nature of this chapter, but the bit about the apple falling is a hint intended to get you to think more about other forms of energy involving gravity.
