The aim of this experiment was to determine how the surface and the height of the ramp affect the distance travelled by the car.

1.Build up a pile consisting of books and plastic containers2.Place one end the plank of wood onto the pile and the other end of the floor to make a ramp3.Measure the height from the top of the plank to the floor4.Place the car on the very top of the ramp, front facing the bottom of the ram and let it go5.Measure the distance travelled by the car and record it6.Place a large napkin, or several small napkins on the plank of wood and repeat steps four and five7.Repeat step six but with paper instead8.Repeat steps one to seven with piles of two different heights

My Prediction

What I think will happen?

I predict that the higher the ramp is the further the car will travel. I also hypothesise that the order in which the car travels from longest to shortest is wood, then the paper and then the napkin.

Results

What happened & Why?

•Small, thin plank of wood•Toy car•Measuring tape•Paper•Napkins•Books•Plastic containers

Materials

The different surfaces of the ramp changed the speed and the distance that the car travelled because of the change in the amount of friction between the tires of the car and the surface of the ramp. The more friction present the slower the car travelled and the shorter the distance travelled. The angle and the height of the ramp also affected the speed and distance that the car travelled.
