Which of the following factors are necessary to calculate power in physics?

• A. Mass, time, and acceleration
• B. Force, distance moved, and time required
• C. Velocity, distance, and mass
• D. Energy, force, and work

Answer: (B)

To calculate power in physics, the correct factors to consider are force, distance moved, and time required. Power is defined as the rate at which work is done or energy is transferred over time. In formulaic terms, it can be expressed as: Power = Work / Time Where work (in joules) is the product of force (in newtons) and distance (in meters) moved. Therefore, when calculating power, it is essential to know both the force applied and the distance over which that force is applied, along with the time it takes to do this work. The other options do not capture the necessary elements for calculating power effectively. For example, mass, time, and acceleration might help determine force using F=ma, but they do not directly compute power. Similarly, using velocity, distance, and mass does not link to power directly, as mass and velocity alone do not provide insight into the work done over a time period. Finally, energy, force, and work are related, but without the time component, they do not yield a formula for power. Hence, focusing on force, distance, and time is crucial in correctly determining power in any physical context.
