Mechanical energy is...

• Potential + Kinetic energy

• Sound + Radiant energy

• Electrical + Thermal energy

When particles vibrate they produce energy that travels in waves to your ear. When these waves reach your eardrums, they vibrate and you hear a sound.

• Mechanical energy

• Thermal energy

• Sound energy

• Sun energy

Energy stored in chemical compounds such as batteries or food

• Chemical energy

• Sound energy

• Radiant energy

• Electrical energy

This energy is produced when a rise in temperature causes atoms and molecules to move faster. It is also known as heat energy.

• Thermal energy

• Radiant energy

• Mechanical energy

• Wind energy

Energy makes things happen, and there are many forms of energy.
