Goal of the experiment: Friction is a force that tries to keep one object from sliding past another. No surface is perfectly smooth, and so there will always be some amount of friction between two rubbing objects.
Materials: - a playmobil jeep
- a ramp
- a smooth board
- a sheet
- a towel
- a fleece blanket
- a ruller, a paper and a pen to note the mesurements
Steps of the experiment: - rolle a Playmobil jeep down a ramp and onto a smooth board
- measure how far past the edge of the board the jeep rolled
- covere the board with a variety of surfaces – a sheet, a towel, and a fleece blanket,
- measure how far past the edge of the board that the jeep rolled off each surface
- made a chart to record this results
We found that the towel created the most friction and slowed the car down the most.
