We made an experiment called Down the Ramp to measure how a force called Friction can effect how quickly a toy car moves down a Ramp.
We made a ramp for a toy car and pushed the toy car down the ramp. We measured how far the car travelled each time.
We then made the surface smoother by using different materials like a laminating sheet and making it rougher by using sandpaper.
Before we pushed the car down the ramp , we made an estimate or a guess of how far it would travel.
We put sandpaper on the ramp to see if it made the car slower or faster! When you look at the results sheet below you will be able to see what happened!
Using a tape we measured the distance that the car travelled down the ramp
Results of our experiment – Down the Ramp
As can be seen from our results sheet above, it was the ordinary ramp with a wooden board that was the fastest. We think this was because it was made out of the correct material for the car to get a grip and move down.
