Energy

Definition: Stored in an object, the ability to move something.


Different kinds of energy: 
Light energy, the energy of electromagnetic waves. 
Examples, microwaves, x-rays, visible light and colors.

Heat energy, caused by the movement of particles. 
Found in all hot objects, fuels such as gasoline and a hot cup of steaming cocoa. 

Sound energy, energy produced by vibrating objects. 
Examples are speech, ultrasound,  and music.

Chemical potential energy, stored in the bonds between particles. Found in substances like petrol and food.

Electrical energy, the movement of electrically charge particles. Found in wires, generators and lighting.

Gravitational potential energy, stored in objects due to their height above the ground. 
Examples are the force that holds the gases in the sun, the force that causes a rock to roll down a hill.

Kinetic energy, caused by the motion of an object. 
Eg. Moving, cars, running, swimming.

Elastic Potential energy, stored in stretched or squashed objects. Examples are springs and rubber bands.
