Energy

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

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
