Meow! https://www.youtube.com/watch?v=qybUFnY7Y8w go to the above link to see a Rube Goldberg contraption. Kinetic energy will be used.
 * Chemical:** a battery could power something to create electricity, a chemical reaction from mentos and coke, vinegar and baking soda reaction.
 * Thermal:** a light is shining threw a magnifying glass magnifying heat catching a rope on fire releasing the the object attached to the rope to drop, a toaster heating something that burns a rope when it pops up, a strong light heating something up.
 * Acoustic:** music played, sound scares something to do something, sound moves something.
 * Electromagnetic:** a light turning on, a light creating electricity through solar panel, a flashlight turning on to complete a circuit.
 * Electrical:** hitting a switch to complete a circuit, an electric toothbrush spinning on something, something powering a fan.
 * Mechanical:** a pulley, a wheel being turned by a motor, an object rolling on a table.

IN the project we will not use friction because when the moving ball hits the stand-still ball, not all the energy is going towards the kinetic energy, some is going towards thermal energy. In the Rube Goldberg project having friction would slow down many of the kinetic and potential energy produced.
 * __Friction and Transfer of Energy:__**

A battery (chemical) powers a circuit (electrical) and lights a light bulb (electromagnetic and thermal). The process of turning on the light with a switch is mechanical energy.
 * __Energy in a closed system:__**

Our project involves chemical, electrical, kinetic, mechanical, and gravitational potential energy.
