Description: Energy can transform between different types, but the total amount of energy always stays the same.
Key Terms: Potential energy, mass, gravitational constant, velocity, jewel, kinetic energy, sound, vibration

The study of various forms of energy and their transformations from one form into another has led to one of the greatest generalizations in physics—the law of conservation of energy:

Energy cannot be created or destroyed; it may be transformed from one form into another, but the total amount of energy never changes.
