How is wind energy classified, and how does it differ from gravitational energy?
I am curious about wind energy. Can you tell me how it is classified and how it differs from gravitational energy?
Sure, wind energy is a type of kinetic energy which is converted from the motion of wind into electricity. It is often classified as a renewable energy source because the wind is constantly replenished by the sun's heat. On the other hand, gravitational energy is the potential energy stored in an object due to its position relative to a reference point. It can be converted into usable energy through methods like hydropower, but it is not considered a renewable energy source.
