The Physics of Car Racing

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

All the cars are all the same.

We all get the same things to add onto our cars.

2 What forces are needed to make the car go faster and how have you modified your car accordingly?

We put play dough on the front of the car because it will weight it down and make it aerodynamic. This is wind resistant so the wind will flow over the car and not stop it.

3 What forces are needed to make the car stop and what adjustments have you made to to try and stop it by the line? 

We need drag to stop the car. So we will put play dough on the back of the car to slow it down

4 What forces are needed to make the car travel further and what adjustments have you made to achieve this? 

A balanced force so we will put play dough evenly around the car.

5  In a google drawing , photograph, your car and clearly show - the forces acting on it

                                                                                                - any changes you have made and 

                                                                                                        how they effect the forces
