Final answer:
The power delivered by a force is calculated as the force multiplied by velocity, which is equivalent to the work done over time. Therefore, Option 2: Force multiplied by speed is the correct way to calculate power in this context.
Step-by-step explanation:
The power delivered by a force is calculated by determining the rate at which work is done. Work itself is defined as the product of force and the distance over which the force acts. However, when discussing power, we look at how quickly this work is done, and time becomes a crucial factor. Hence, power is calculated as the work done divided by the time over which it is done (power = work/time).
In a scenario where a force is applied to a particle causing it to move at a constant velocity, the power delivered is the dot product of the force and the particle's velocity. Since work is force times distance (w = Fd), and velocity is distance divided by time (v = d/t), we can also express power as the force multiplied by velocity (power = Fv).
Therefore, among the options provided, the most accurate description of power delivered by a force is Option 2: Force multiplied by speed, assuming speed and velocity are used interchangeably in this context and the force is acting in the direction of the motion.
