Circle the correct answer:
Energy is often defined as the ability to do work. There are two main types of energy: potential
and kinetic. [Potential/Kinetic] energy is stored energy. Think about a spring that has been
compressed. It contains [Potential / Kinetic ] energy. [Potential / Kinetic] energy is energy in
motion. The moving parts in an engine show [Potential/ Kinetic ] energy. These two types of
energy can be in several different forms.
