okay first question is you are a passenger in a car at night. describe the energy transformation that are taking place to power the car's headlights.

second the propeller is not turning. it has no (potential/kinetic) energy. the third one is the coiled rubber band stores (potential/kinetic) energy. fourth when the propeller is released the rubber band uncoils. as a result, the propeller turns, and, (potential/kinetic) energy is transformed into (potential/kinetic) energy.

if ANY describe (on all of these) the energy transformations.

 the driver pumps the gas from the gas tank into the car.

the driver starts the car. in the engine a spark causes a small amount of the gas to explode. the explosion breaks down the fuel into smaller particles and produces heat in the engine.

the process of lighting the bulb at night, chemical-to -electrical energy- to- Heat- to- light.

the propeller has no kinetic energy

the rubber stores potential energy

when the propeller since potential energy is turned to kinetic energy

driver pumps the gas; chemical energy - to thermal energy- to mechanical energy

the driver starts the car; chemical energy- to- thermal energy- to - mechanical energy

explosions breaks down the fuel ; chemical energy- to- thermal energy-to- mechanical energy.
