Chemical energy is the energy stored in the bonds of atoms and molecules. Food and fuel are examples of chemical energy.

​

The energy can't be used until the bonds are broken.

​Chemical Energy

Nuclear energy is the energy stored in the nucleus of an atom - the energy that holds the nucleus together. The energy in a plutonium atom is an example.

​

The energy can't be used until the bonds are broken.

​Nuclear Energy

​

Elastic energy is stored in objects by force. Compressed springs and stretched rubber bands are examples.

​

The energy can't be used until the force is broken.

​Elastic Energy

​

Gravitational Energy is the energy of place or position. Someone at the top of a slide has greater gravitational energy because they are higher.

​

The energy is based on how high you are above earth's surface.

​Gravitational Energy

​

Radiant energy is electromagnetic energy that travels in transverse or light waves. Lights and x-rays are examples.

​

This energy is always in motion.

​Radiant Energy

Thermal energy or heat is the internal energy in substances - the vibration of atoms in substances. The heat from a fire is an example.

​

This energy is always in motion.

​Thermal Energy

​

Motion is the movement of a substance from one place to another. Wind and moving water are examples.​

This energy is always in motion.

​Motion

​

Sound is the movement of energy through substances in longitudinal or sound waves. Echoes and music are examples.

This energy is always in motion.

​Sound​

Electrical energy is the movement of electrons. Lightning and electricity are examples.

This energy is always in motion.
