Wind Car 4 (Windmill Type)

Let's take a look!

Watch the video on YouTube.

What kind of experiment is this?

Experimental procedure and explanation:

• This wind car utilizes a windmill. It has a simple configuration that uses a rubber band to transmit rotation.
• Windmills have more resistance than propellers, but you can see how these familiar devices can move the car forward.
• In wind power generation, propellers are used because windmills have more aerodynamic drag.
