What is a windmill? How can it be used?
Energy transformation:
Transforming one energy form into another is described as energy transformation. The mechanical energy can be transformed into potential energy. Similarly, thermal energy can be changed into heat energy.
Windmill:
It is a structure that transforms wind energy into kinetic (rotational) energy. It is done by using blades, vanes, etc. It utilizes the energy of moving air or wind.
Uses of windmill:
It can be employed to generate power. It can be used in groundwater pumping, irrigation, grinding grains, drainage pumping, tobacco processing, etc.
