The Physics of Car Racing

The  Physics of Car Racing

1.What has been done to make this a 'fair test'?
We all had the same type of model car to start off with. Also we are racing our cars in the same track and the same materials to use.

2.What forces are needed to make the car go faster and how you modified your car accrodingly?
We added rock and clay to increase the gravity to make it go faster. The gravity pushes the car down on a angle which accelerate it.

3.What forces are needed to make the car stop and what adjustment have you made to try and stop it by the line? We added rubber bands and wrapped it around the car to make it bumpy have more friciton.

4.What forces are needed to make the car travel further and what adjustments have you made to achieve this? To have more acceleration but less gravity. So we took the rock off so there's not much gravity as before. We still need a little bit of weight on top of the car so it's balanced and won't be able to flip so we kept the clay.
