        In the forces and motion experiment the cars went much farther than I thought.My prediction  was true because the car went  farther on the tile than on the carpet.

        I think the reason why the car went farther on the tile is the carpet has more friction and it is rough and bumpy while the tile is soft and smooth.

      I was surprised how far the car went on both surfaces. The result on the carpet was 270 centimeters and on the tile it was 374 centimeters. Which means the difference was 104.
