Which equation correctly defines power in terms of work and time?

Power is defined as the rate at which work is done, and this rate is determined by how much work is completed over a certain period of time. The correct equation that encapsulates this relationship is expressed as Power = Work / time.

In this equation, 'Work' represents the total energy transferred or the total task accomplished, while 'time' refers to the duration over which this work is performed. Therefore, when you divide the amount of work by the time taken to do that work, you get a measure of power, which is typically expressed in watts in the SI system.

This reflects the principle that if more work is done in a shorter amount of time, the power output is greater. Conversely, if the same amount of work takes longer, the power would be lower. Understanding this equation is vital in various fields of engineering and physics, as it illustrates how efficiently work is performed.
