Physics of car racing

What I tried today: I tried adding a spoiler and a lip spoiler onto our car for downforce.

What happened when I tried it: When I tried the spoiler and the lip spoiler the car went fast down the slope and slow down when it lost its momentum.

What will I try next time: Next time I will have a go at the new dragon style addition seems that they will work.

What research did we do: We researched what kind if additions they have on sprint cars and why they work

1.What has been done to make this a 'fair test'? We have all gotten the same car, the same materials and the same track to race on

2.What forces are needed to make the car go faster and how have modified your car to go accordingly? We need gravity for the slope and we have added a spoiler for downforce and it will hopefully keep it straight

3.What forces are needed to help the car stop and how have you modified your car to go accordingly? We have added wings for drag and the drag will hopefully slow the car down

4. What forces are needed to help the car go further and how have you modified your car to go accordingly? We need thrust to push our car and we have added a front lip spoiler to increase aerodynamics
