Create and Improve #2

Day 4:

I finalized by 1st prototype which was an energy potential car. The materials included rubber band (7 cm), 2 CD disk (radius 6 cm), long wooden stick (9.3 cm), short wooden stick (3.3 cm), and 2 pieces of cardboard (11 cm by 5 cm).

The way the car works is by spinning the wooden stick in one direction so that the rubber band is going to be tied between the two CD disks which creates elastic energy. When released on the ground after spinning the wooden stick, the car will transfer elastic energy to a kinetic energy having the car to move in a certain direction.

 

My intended scenario was to have the energy potential car to move forwards after spinning the wooden stick in one direction. However, the energy potential car was spinning in circles which meant that there was a significant problem during the process of making the car. Next class, I would need experiment with different dimensions or resources of materials that can help the energy potential car to move forwards.
