    13 Examples of Kinetic Energy in Everyday Life – StudiousGuy

    Wind Mills. Windmills form one of the good examples of appliions of kinetic energy. In a windmill, when the wind (air in motion) hits the blades, it causes the rotation, which ultimately leads to the generation of electricity. Here, the moving air has kinetic energy that causes the rotation of blades, and therefore, in this example too, the ...
