What caused the turbine to spin?

Turbines catch the wind’s energy with their propeller-like blades, which act much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn.

How do you make a pinwheel spin faster?

It takes a certain amount of wind to get the pinwheel spinning. (Students may be able to identify that the force of the wind has to overcome the forces of gravity and friction that are also acting on the pinwheel.) The faster the wind speed; the faster the pinwheel spins.

Can wind turbines rotate?

Wind turbines can rotate about either a horizontal or a vertical axis, the former being both older and more common. Horizontal-axis wind turbines (HAWT) have the main rotor shaft and wind generator electrical generator at the top of a tower, and must be pointed into the wind.

What type of energy is present in the moving paper windmill?

Windmills are machines that convert kinetic energy (wind) into mechanical energy.
