Elastic Powered Hybrid Car
We had to create a hybrid car that doesn't use chemicals. Mackenzie came up with an idea to slam two pieces of wood together with some rubber bands. . We worked on this project over a span of 3 weeks. 1 week of design, creation, and presentation.

Kinetic Energy- energy due to motion. The equation for Kinetic Energy is KE=1/2 x mass x velocity squared
Spring Constant- a measure of how easily a spring is compresses and expanded. To find this we used Spring Constant=Force/Distance
Thermal Energy- potential energy converted into heat energy
Total Energy- the total amount of kinetic, potential, and thermal energy in a moving object

Reflection
This was a hard project to complete. The design Mackenzie came up with took a while to build. First we had to wait for the drawer rails to come in from Amazon. Then we had to find rubber bands that were strong enough. Our car had two parts. One part was pulled back then slammed into the other. This caused all potential energy to be lost within the first second of movement. Our car just didn't have enough kenetic energy to move it 5 meters. We could reliably go 3 meters. Our car did have the fastest start speed and acceleration. We just couldn't maintain it.
