Energy

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

Diffrent kinds of energy.

- Light energy = The energy of the electromagnetic waves. Found in all Micowaves , Xrays and visble light. (flash light , candle)

- Heat enery = caused by the movement of particles. Found in all hot objects (  solar system , Heat energy)

-Sound energy =  Energy produced by vibrating objects. Examples are speech,ultrasound and music. ( solar , wind)

-Chemical potential energy = Energy stored in the bonds between particales. found in substances petrol and food. ( food , batteries)

-Electrical energy = the movement of electrically charge particles. found in wires generators and lighting.(Direct current , lighting)

-Gravitational potential energy   = Energy stored in objects due to their height above the  ground. (Airplan , Rocket)

-Kinetic energy = Energy due to the motion of an object. eg. moving cars, running, swimming

-Elastic pontentail energy = Energy stored in stretched or sqauashed objects. Examples are springs and rubber bands.
