Question

The blades of a wind turbine are at rest until the movement of air causes the blades to spin.
Which energy transformation happens when the blades are spinning as shown?

Answer 1

When the blades of a wind turbine are spinning due to the movement of air, there is a transformation of energy occurring. Specifically, the kinetic energy of the moving air (wind) is converted into mechanical energy as it causes the turbine blades to rotate. This mechanical energy can then be transformed into electrical energy by the generator connected to the turbine, making it potential energy for storage or use in electrical applications.

So, the primary energy transformation happening when the blades are spinning is from kinetic energy of the wind to mechanical energy of the rotating blades.
