The Physics Of Car Racing

1.What has been done to make this a 'fair test'

• They all have to drive forward.
• We all have a selection of choice of what materials we want on the car.
• All the cars are the exact same.

2.What forces are needed to make the car go faster and how have you modified your car accordingly?
Gravity and thrust are the forces of the car to make it accelerate to the green line.The lift makes it stay on the ground so it doesn't flip of go off the track.  


3.What forces are needed to make the car stop and what adjustments have you made to try and stop it by the line?
Gravity and drag.We have added more weight onto the back which the gravity keeps it down.The car and the wheels front and back drag makes it go slower.

4.What forces are needed to make the car travel further and what adjustments have you made to achieve this?
We need thrust,gravity and lift to make it go further the thrust helps by pushing it down all the way to the end of the track.
