Alternate Energy Vehicle

Evidence of Work

Process of Making alternate Energy Vehicle

The process of making this vehicle took a total of around three weeks. We first started with prototype one which did not work because there was too much friction due to the axle being wood vs. wood. Our next step was to restart and make prototype two, here we changed the base of the car and made it longer and much skinnier. We added a small wheel with metal axles. We could not get a way to make the vehicle go so we added two pegs on the outside of the vehicle, then we added two small pieces of straw for the axle to go through. After that we added a nail in the front of the car to power it with four rubber bands, this did not work because there was too much friction between the wheels and the surface. So our next modification was to add bigger wheels, we added four cd's glued together for both wheels in the back and two cd's for the wheels in the front. Our next step was adding a Pvc pipe to hold our two passengers. Our last steps were converting to three rubber bands and adding a screw to the front.

Content

Spring Potential Energy- (Potential energy caused by a spring) You can see this in our car when looking at the rubber band when it is not being unwound at all

Gravitational potential Energy-(an energy that is related to gravitational force or gravity) This is not shown because we used spring potential energy instead.

Kinetic Energy-( An object that is in motion) This is shown when the rubber band is getting unwound and the car is moving.

Total Energy-( This is all the energy added all together) You would see this when potential energy  is present.

Distance Vs. Time-(This is a graph that shows the distance something has traveled over some time.) This is represented in our vehicle because, over 16 seconds, the care traveled 5 meters which is in our distance vs. time graph.

Velocity Vs. Time- (This is how fast or slow an object is when in motion) You can see this in our vehicle when it starts to accelerate, It is the speed of our vehicle.

Rotational Inertia-(A property of any object that can be rotated.) There is rotational inertia in are axle's that are attached to are wheels.

Reflection

During this project, two things I did very well were cooperating and solving problems. I think that I cooperated very well during this project and we all got things done, and also we all cooperated well because we got our vehicle done very quickly because we all talked and solved problems. The next thing I believe that I did well was solving problems, for example, our prototype failed very badly and we had to solve many problems to get it to work. Out of this project, two things I would like to improve on are critical thinking and conscientious learning. First off is critical thinking i wish that I worked harder and thought harder to make our car go faster than it is I also think that during this project I wasn't a great critical thinker. Lastly, I wish I was more of a conscientious learner because I think I could have been more organized before starting the project by having a good rough draft and following it.
