What is the unit of power?

The unit of power is the Watt. Power is defined as the rate at which work is done or energy is transferred over time. One Watt is equivalent to one Joule per second, which quantifies how much energy is emitted or used in a given timeframe. This measurement is crucial in various fields, including aviation, where power influences the performance of engines and electrical systems.

The other options represent different physical quantities. Joules measure energy, Newtons are units of force, and Pascals (Pa) represent pressure. While all these units are important in their respective contexts, the Watt specifically relates to the concept of power and is widely used to express electrical power, mechanical power, and energy consumption in various applications.
