Transportation Science Fair Project

Friction and Speed

Medium
Friction and Speed | Science Fair Projects | STEM Projects
This science project explores how different surfaces affect the speed of cars. We will measure the time it takes for cars to travel two meters down a ramp with different surfaces. We will then compare the results to see how the surface affects the speed of the cars.

Hypothesis

The hypothesis is that cars move faster on a fine surface and more slowly on a coarse surface.

Method & Materials

You will set up a ramp with different surfaces, measure the time it takes for cars to travel two meters down the ramp, and compare the results.
You will need a ramp, three types of model cars, seven pieces of sandpaper with different grit sizes, a stopwatch, a ruler, an assistant, and masking tape.

Results

The results showed that as the surface of the ramp became more coarse, the cars took a longer time to travel two meters down the ramp. This observation stands out and supports the hypothesis that cars move faster on a fine surface and more slowly on a coarse surface.

Why do this project?

This science project is interesting because it explores how different surfaces affect the speed of cars. It also shows how friction plays an important role in the motion of cars.

Also Consider

Experiment variations include using remote controlled cars and increasing the gradient of the ramp.
