Description:
In this project we have to build a functioning car that runs exactly 5 meters with the best efficiency. In the car we can not use any energy source that is currently used in car today for example fossil fuel, gasoline, soler etc. we used a rubber band to power our vehicle, we had the rubber band tied to one axle and attach the end of the rubber band to a stick at the end of the car, then we wind up the rubber band and release it, the car will start moving forward.

Concepts:
In this project we learned many new physics concepts that is very impotant. The following the concepts we used in our car.
spring constant(K): The measure of how difficult it is to expend or compress the spring. This equation will help us to find the spring potential energy. We used the equation K=F/d.
spring potential energy(PEspring):The energy stored in a spring when it is compressed or expanded. We used spring potential energy to find the starting potential energy and the total energy of our car. We used the equation PE=(1/2)Kx^2 when x= the distance the spring is compressed or expanded.

Reflection:
This project went acceptable overall. I was able to organize my team reletively well by frequetly encourging the team that we can do this. I also gained the ability to find and fix problems which helped when our prototypes had problems moving.
This project was an acceptable project because not everything went smoothly. I could have kept a more positive attitude when my group's efforts don't work in a good way especially when prototypes don't work well. Our time manage was pretty bad, so I will try to do this by evenly distribute our work and priortize some over the other. Another solution to improve this is to make sure that every one is on task.
