WebIf the work it takes you to climb the stairs is 1000 joules, then we can calculate the power in both cases P 1 (running) and P 2 (walking): Power = W/t. P 1 = 1000 J ÷ 5 s. P 1 = 200 … WebJul 15, 2024 · Since work is force times displacement (W=F*d), and velocity is displacement over time (v=d/t), power equals force times velocity: P = F*v. More power is seen when the system is both strong in force and fast in velocity. Units of Power Power is measured in energy (joules) divided by time.

WebExpert power is based on the perception that a person is highly qualified in a particular field. For example, a surgeon has expert power in medical matters relating to a patient. It is important to note that expert power is about the perception of knowledge rather than the actual knowledge itself. WebPower in its simplest form is the product of force multiplied by distance, divided by time. In a sporting context, force can be substituted for strength, and time/distance indicated by the speed of movement.
