Energy is the ability to cause change or do work. It is all around us and involved in every movement, sound, and process. From the heat of the sun to a flashlight being turned on, energy is constantly being used, transformed, and transferred.
Energy cannot be seen directly, but its effects are visible. It can make things move, heat up, give off light, or produce sound.
1. Forms of Energy
Energy is the ability to do work or cause change. It exists in many forms and can be observed through its effects on matter. Each form of energy behaves differently and can be identified through real-world examples.
Kinetic energy
This is energy due to motion. The faster an object moves, the more kinetic energy it has. All moving objects—large or small—possess kinetic energy. Examples:
