Rolling on Inclined Planes

Rolling on Inclined Planes | Science Fair Projects | STEM Projects
We're going to find out how different surfaces affect how far and fast a matchbox car rolls down an inclined plane. We'll measure the distance the car rolls on different surfaces and compare the results.


The hypothesis is that a matchbox car will roll farther when the inclined plane is covered with wax paper than when it is covered with sandpaper or aluminum foil.

Method & Materials

You will make an inclined plane 6 cm high on the floor, roll a matchbox car down the inclined plane with nothing on the inclined plane, and record the distance it rolls. You will then cover the inclined plane with sandpaper, wax paper, and aluminum foil and repeat the experiment.
You will need a matchbox car, a measuring tape, wax paper, sandpaper, aluminum foil, and a data collection sheet.


The results showed that the car rolled the farthest when the inclined plane was covered with aluminum foil. This observation stands out because it was unexpected.

Why do this project?

This science project is interesting because it shows how different surfaces can affect how far and fast an object rolls.

Also Consider

Experiment variations to consider include testing different heights of the inclined plane and testing different objects.
