The first prototype was experimented. However, the energy potential car was spinning in circles which wasn’t my expectation.
The above movie shows the car spinning in circles.
During the process:
After making a few changes, I re-experimented my prototype which was a success. The energy potential car moved forwards in a steady position which was my expectation. By having the wooden stick spinning, it would have the rubber band to curl around and create elastic energy. As soon as I let go of the car, it would start moving forwards using kinetic energy. This shows the energy transfer of elastic energy to kinetic energy.
The above movie shows the car going in a straight direction.
