What is the formula for calculating power?

Work = Force × Distance
Power = Work/Time
Power = Force/Distance
Power = Energy/Time

The correct answer is: Power = Work/Time

The formula for calculating power is defined as the rate at which work is done or energy is transferred over time. Therefore, power can be expressed as the total work completed divided by the time it took to complete that work. This relationship is captured in the equation Power = Work/Time. This formula highlights the concept that if more work is done in a shorter period, the power output is greater; conversely, if the same amount of work takes longer to complete, the power output is less. This definition of power is fundamental in both mechanical systems and in electrical contexts, where it indicates the efficiency and speed of energy conversion or work done. The other choices reflect different concepts in physics but do not accurately define the relationship that describes power specifically. Work is calculated using Force and Distance, but that does not relate directly to power without incorporating the time variable. Power can also be associated with energy, but the correct expression for power itself directly connects to work done over time. Thus, the accurate and relevant formula for power in this context is indeed Power = Work/Time.
