Car

1. What problems does  our car already have?

•  It turns when landed on the flat ground. (We can make the front part heavier because the car’s back is heavier. So it has a balance force)

• Sometimes it does a flip. (adjust the angle of the ramp. 150 degrees)

2.How do you think will make your car go faster?

To make the car heavier so there's more gravity pushing it down the ramp.

3.How do you think you will slow your car down?

Put sand paper just before the end of the green lign.

4.What equipment will we need?

• Stone
• Sandpaper.
• Clay
• rubber mands

When we placed the rock in the middle of the car it flippped so we decided to move it more forward, the first try it did it perfectly but the second try flipped again. It isn'y accurate maybe we could try a different strategy.

We decided to modify the car by putting rubber bands in the middle of the car so it has more friction so it can slow down.
