Alternative Energy Powered Car
Project:
We had to build an energy efficient car without using fuel. It had to go a distance of five meters and stop on its own. It took many ideas to come up with the one we ended up with. Our group built many different prototypes. We changed our prototypes completely from using all different sorts of energy. For ours we ended up using a rubber band powered car which was our original design. The car had four wheels and an axel to connect them across the body. The rubber band was connected to a screw and hooked onto a screw on the back axel. It got power by winding up the rubber band and flinging the car forward by the unraveling of the rubber band. As our final design was wound up and ready to be launched, we all watched. As it stopped at the five meter mark we all jumped and got really excited.
Reflection:
Our group worked pretty well together. I learned a lot about cars and how they move. We all put our ideas in well together. I did the calculations, Dalton did the building, and Archer did the graphs and power point. When it was all put together it turned out really well. I could still work on paying more attention to the project. Also, by being more into the project. We did have a little trouble splitting up the work. In the end it all worked out and was a fun project.
Concepts:
Mechanical Advantage- force amplification applied from a tool
Friction- the force opposing on an object
Mass- the weight of an object
Acceleration- the rate at which an object increases velocity with time
Velocity- a speed in a given direction
