Energy - Science

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

Different kinds of energy:

1-Light energy ( The energy of the electromagnetic waves. Found in microwaves, x-rays and visible lights.)

Example: Burning candle and light bulb.


2-Heat energy ( Caused by movement of particles. Found in all hot objects.)

Example: The sun and stovetop. 


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

Example: Balloon Popping and airplane taking off.


4-Chemical potential energy ( Energy stored in the bonds between particles. Found in substance like petrol and food.)

Example: Gasoline and batteries. 


5-Electrical energy ( The movement of electrically charge particles. Found in wires, generators and lighting.)

Example:Lightning and batteries. 


6-Gravitational Potential energy ( Energy stored in objects due to their height above the ground.)

Example: Water that is behind a dam and a raised weight. 


7-Kinetic energy ( Energy due to the motion of an object. Eg, moving cars, running, swimming.)

Example:Bullet from gun and Roller Coasters. 


8-Elastic Potential energy ( Energy stored in stretched or squashed objects. Examples are springs and rubber bands.)

Example: A bent diving board before the diver jumps and an archers stretched bow.
