What is the Power Equation as described in the material?

• A. Work / time
• B. Task x resistance / time
• C. Force x velocity
• D. Energy / time

Answer: (B)

Power is the rate at which work is done. In the material, work is expressed as the distance you move a resistance times the force (distance is called Task, force is called Resistance), and power is that amount of work divided by the time it takes. So the described equation is Task × Resistance ÷ time. Since work equals force times distance, dividing by time gives power, which matches the standard idea that power equals work over time. If you test it with numbers, moving a 4 N resistance a distance of 3 m in 2 seconds gives Power = (4 × 3) / 2 = 6 W. This form directly uses the material’s terminology, but it’s the same idea as P = W/t or P = F × v, since v = d/t.
