The goal of the Alternative Energy Vehicle was to create a car that goes as close to 5 meters as possible using a uncommon method. For example we couldn't use a gas engine, but we could use an rubber band.
Our car works by pulling a rubber band. This is done by wrapping the band around the back wheel axle. It is then unraveled by pulling on the axle. This causes the car to pull forward. It pulls for the entire time it's driving and bumps into a wall to stop. One way we could improve our design is by using pvc pipe instead of wood for the frame. Its one, lighter and two has less friction on the axle.
Calculations
Spring Potential Energy
Spring Potential Energy is the amount of potential energy the band has from its stretch.
Gravitational Potential Energy
The gravitational potential energy is the amount of PE from gravity.
Kinetic Energy
KE is all the energy due to motion
Total Energy
The total energy of the system
Thermal Energy
The energy that is due to friction or heat.
Rotational Inertia
Is the amount of mass near the center of the wheel.
