Forms of Energy

By Kristi Collins

Mechanical Energy

Definition- form of energy associated with the position and motion of an object.

How to find mechanical energy: Mechanical energy = Potential energy + Kinetic energy


1.) The football being thrown in the air has mechanical energy.

2.) A moving car

Thermal Energy

Definition- the total amount of potential and kinetic energy of the particles in an object.


1.) Lava flowing out of a volcano.

2.) The sun.

Electrical Energy

Definition- the energy of electrical charges.


1.) Electrical charges in lightening

2.) Electrical lines along highways carry electrical charges

Chemical Energy

Definition- the potential energy stored in the chemical bonds that hold chemical compounds together.


1.) There is chemical energy in grapes that can be used for later energy.

2.) Firewood has chemical energy that is released as the wood is burned.

Nuclear Energy

Definition- type of potential energy that is stored in the nucleus of an atom

The energy is released during a nuclear reaction.


1.) The sun is a source of nuclear energy.

2.) The atomic bomb.

Electromagnetic Energy

Definition- a form of energy that travels in waves.


1.) Food being heated in a microwave.

2.) Any visible light is an example
