The formula for power is defined as the rate at which work is done or energy is transferred over time. Power quantifies how quickly work occurs and is expressed in watts (W) in the International System of Units (SI). Specifically, work is the product of force applied and the distance over which it is applied, but when considering power, time becomes a critical factor. By using the formula P = Work/Time, it clarifies that power is generated when a certain amount of work is accomplished within a specific time frame. This is fundamental in various fields, including physics and engineering, as it allows understanding of energy efficiency and the performance of machines.

Other formulas, such as those related to force, mass, and velocity, provide different physical principles but do not define power in the context required. Understanding how power relates to work and time is essential in many practical situations and problem-solving contexts within nursing and healthcare scenarios, especially when considering the efficiency of processes or interventions.
