We tested the effects of friction on a toy car. We made a ramp for the car, and we timed the car on different surfaces. We used materials such as wood, felt, foil, plastic, and construction paper. We found that rough surfaces create more friction for the car, and smooth surfaces create less friction for the car. Some of the surfaces even caused the car to stop completely. Watch our video to see our experiment!
