Energy: the ability to do work

Work: happens when a force causes an object to move in the direction of the force. Example: If you kick a soccer ball, it moves in the direction of that force

Kinetic Energy What is kinetic energy? Energy of motion All moving objects have kinetic energy

Potential Energy How is potential energy different from kinetic energy? Energy an object has because of its position or shape

Thermal Energy Total energy of the particles that make up an object At higher temperatures, particles move faster

Chemical Energy The energy stored in a substance that can be released when the substance reacts.

Electrical Energy Energy of moving electrons Electrons are negatively charged particles and move back and forth in the wires. As they move energy is transferred to different parts of the appliance.

Sound Energy Caused by vibrations

Caused by the vibrations of electrically charged particles. Light Energy Caused by the vibrations of electrically charged particles.

Nuclear Energy Energy caused by changes in the nucleus of an atom Happens when two or more nuclei join together or when the nucleus splits
