## anonymous one year ago I just pulled up to Sheetz and filled my car up with gas. Explain the transfer of energy that would occur once I start then drive my car--consider the type of energy that exists within the gas molecules, explain the transfer of form of energy as gas is burned and I drive my car, and consider how the engine and tires may feel after I have traveled in my car. (Use the following terms in your explanation: potential energy, kinetic energy, friction, and heat.)

Gas in tank is volatile -- potential chemical energy Gas injected into chamber and ignited - kinetic chemical energy Explosion pushes on pistons - mechanical kinetic energy Pistons turn transmission and transmission turns wheels - mechanical kinetic energy Not all energy can be converted to mechanical to turn the wheels, some heat is lost in the connection between the piston, the transmission and the wheels through friction. When the wheels turn, the mechanical force of the wheel pushes against the ground. The ground pushes back causing the car to go forward. The wheels will experience a rotation and some compression which results in heat on and in the wheel. The contact force between the wheel and the road experiences some heat due to friction. Without friction, the wheel would just turn like on ice, so friction is required. Does this help? Picture is just a bonus ;-) |dw:1435609227448:dw|

gurlll, I @ you several times on twitter for a reason, but you CHOSE to ignore me... so I'm telling the teacher what you've been doing (cheating) and we'll see if you continue to ignore.
