Learn on PengiAmplify Science (California) Grade 8Chapter 1: What Is Energy?

Lesson 3: Kinetic and Potential Energy

Key Idea.

Section 1

Kinetic Energy

Key Idea

Moving objects possess a specific form of energy known as kinetic energy.

This is the energy inherent in motion. A spinning generator handle, a falling rock, or a walking person all demonstrate this energy type.

Section 2

Potential Energy

Key Idea

Objects store energy based on their position or condition. This potential energy gives an object the capacity to move or change at a later time.

A battery holds potential energy in chemical form, ready to power a light. Similarly, a lifted weight possesses potential energy due to gravity. Even stationary objects hold this energy, which remains available for future release to perform work.
