WHAT IS ENERGY?
DEFINITION: Energy is the ability to do work.
People use energy for everything from making a jump shot to sending astronauts into space. There are two types of energy:
- Stored (potential) energy
- Working (kinetic) energy
For example, the food a person eats contains chemical energy, and a person's body stores this energy until he or she uses it as kinetic energy during work or play.
