Moving air (wind) possesses (kinetic/ potential) energy

Text Solution

AI Generated Solution

To determine whether moving air (wind) possesses kinetic or potential energy, we can analyze the characteristics of moving air. ### Step-by-Step Solution: 1. **Understanding Energy Types**: - Kinetic energy is the energy of an object due to its motion. It depends on the mass of the object and the square of its velocity. - Potential energy is the energy stored in an object due to its position or configuration. It is often associated with height in a gravitational field. ...
