Kinetic+and+Potential+Energy

Kinetic Energy


The energy in moving objects. Also called movement energy. > Every moving object has kinetic energy (sometimes called movement energy). The more mass an object has and the faster it is moving, the more kinetic energy it has.
 * **Bigger and faster**

Gravitational Potential Energy
= = = = Stored energy in raised objects.

Elastic Potential Energy
== Stored energy in stretched or squashed objects. > Elastic objects such as elastic bands and squash balls can change their shape. They can be stretched or squashed, but energy is needed to change their shape. This energy is stored in the stretched or squashed object as elastic potential energy
 * **Stretching and squashing**

**ENERGY TRANSFER __Boucing Ball__**
Loads of transfers happen when a squash ball is dropped onto a table and bounces up again.



GPE = Gravitational Potential Energy KE = Kinetic Energy EPE = Elastic Potential Energy


 * 1) When the ball is first above the table (stationary) it has maximum **GPE** but no **KE** or **EPE**.
 * 2) **As the ball falls its GPE transfers to KE. The ball then accelerates towards trhe table.**
 * 3) When the ball has hit the table the **KE** transfer to **EPE** as the ball squashes. The ball then obviously regains its shape and bounces back up due to the **EPE** being transferred into **KE**.
 * 4) The ball the reaches its highest point therefore all the **KE** has transferred to **GPE.**

For another example of energy transfer click this link below :D....
 * //Note that the ball will be lower than it was when it was first dropped, because some energy is also transferred as heat and sound to the surroundings.//
