Research Paper On Rubber Band Car

The original design for the rubber band car was a three wheeled car powered by the back axle. My group decided to change the car into a more unique car and ended up with a wind powered car with a water bottle as the base of the car.

With the water bottle as the base, there are four metal tin lids as the wheels with a straw in the center of the whole to cause less fiction. Then the skewer sticks go threw the straws which all are connected to the bottom of the water bottle. With balloons on the four tin lids for traction to have the wheels move smoothly. A skewer stick poking out of the front of the water bottle to hold the rubber band at a certain degree so it can release more energy into the car. With the propeller strapped to the back of the water bottle with duct tape and a skewer stick to keep the propeller in place. The skewer stick that is connected to the propeller goes down the middle of the water bottle and is taped to the top of water bottle. With the rubber band going down the water bottle, (the rubber band is not stretched out) we twisted the propeller to the right until the rubber band gets really tight then we let it go and the car moves around four …show more content…
The car doesn't lose or gain energy meaning the law of conservation is followed. The car begins with kinetic energy then turns to potential energy from the rubber band. It pushes the car which is kinetic energy then later turns to potential when finishing the last spins from the free acceleration. The Newton's first law, stays at rest if at rest and if an external force makes it move it moves. The car moves from the external force which is the rubber band and stays at rest if at rest. Newton's second law, the car moves with an external force which is the rubber band. Newton's third law, because of gravity from the earth the car stays on the ground and has a force towards earth and the car pushes toward the
