Question: 1 / 400

How is power (P) related to work done (W) and time (t)?

W ÷ t

Power (P) is defined as the rate at which work is done over time. This relationship can be expressed through the formula P = W / t, where P represents power, W represents work done, and t represents the time taken to do that work.

In this context, power quantifies how fast work is being accomplished—in other words, how much work is done for each unit of time. Therefore, when work is divided by the time taken, the result gives us the average power output.

The other options do not accurately reflect the relationship between power, work, and time. For instance, multiplying work by time, subtracting time from work, or dividing time by work would not yield a meaningful measure related to the definition of power in physics. Hence, the correct relationship is captured by W ÷ t.
