What is our car?
Our car Steve, is a car that is top heavy and uses that weight to go faster and further down a ramp. The goal is for our car to go 5 meters and stay exactly at that. We had to change our mass constantly in order for it to be just right. For our car, we decided to go with a medium size wood base, four wood wheels with the two wood axles, and a very heavy top heavy front. We decided to go top heavy to help increase the speed for our car as it goes down the ramp to try to carry the pennies 5 meters safely. At first thought we were going to do a rubberband car, but it caused too much of friction and tension, and only slowed it down. The results hanged massively as the car went from 1 meter to 4-5 meters.
What did we do?
We had to at first brainstorm ideas on our car and what it would be. We then had to make a blueprint of the car. The next part was to build our car. We made our car out of wood and rubber bands. After all that, we then tested the car and found the physics. My groupJada and Chase did a great job and I feel that we divided up the work evenly.
Physics
We has to find the energy of the car and here is what we got:
PE: 1.35 J
KE: 2.70829125, 1.203685, 1.047285, 0.68087125, 0.257125 (Different each meter)
Total Energy: 1.35 J
We also had to have three different graphs which were distance vs time, velocity vs time and an energy graph:
PE: 1.35 J
KE: 2.70829125, 1.203685, 1.047285, 0.68087125, 0.257125 (Different each meter)

Our car took a lot more work than I thought it would, but I’m the end it ended up working. My group was one of the better groups I have had and I am glad I got to work with them. I am proud of what we did and can’t wait to start the next project.
