The goal of this project was to create a car with maximum efficiency and use it to find out if the energy supplied by the fan's power would equal the car's final kinetic energy. To make the car work, we would attach wheels and a fan to the car that would propel the car forward. To measure the kinetic energy of the car we measure its distance on a motion track, its time using a sensor, and other variables by either measuring them or calculating them using other variables.
