When water is moving, it has a combination of both potential energy and what?

When water is in motion, it possesses kinetic energy, which is the energy of motion. This is important in the context of firefighting because understanding water's kinetic energy can help firefighters estimate how it behaves when applied to extinguish a fire, especially in terms of nozzle pressure and water flow rates.

Potential energy, on the other hand, is the energy stored in an object due to its position or state, such as water held in an elevated container. When water moves, it not only has potential energy related to its position but also has kinetic energy due to its velocity. The interplay between these forms of energy influences how water can be effectively used during firefighting situations, contributing to the overall effectiveness of fire suppression.

The other concepts, like oppositional or transverse energy, do not apply in the context described, and static energy typically refers to energy possessed by a body at rest, which is not relevant when the water is actively moving. Thus, kinetic energy is indeed the correct term to describe the energy associated with moving water.
