Final answer:
3) power.The correct answer to the question is power, which is the rate at which work is performed or energy is transferred. The required power is greater when the same amount of work is done in a shorter time frame.
Step-by-step explanation:
The correct answer is option 3) power. When a job is accomplished more quickly, the same amount of work is done, but the power required is greater. Power is defined as the rate at which work is done or energy is transferred.
Whether the task takes a short time or a long time to complete, the same amount of energy might be expended, but the power output during the time frame is different. For instance, lifting a weight from the ground to your shoulder can consume the same amount of energy whether you lift it slowly or quickly;
however, lifting it quickly requires more power because you're doing the same work in less time.
The correct answer is option 3) power. While work is the amount of energy transferred by a force over a distance, power measures how quickly that work is done.
Two jobs that require the same amount of work can still have different amounts of power depending on how quickly the work is completed.
For example, if two people are carrying the same load up a flight of stairs, the person who reaches the top first is exerting more power because they are doing the same amount of work in less time.
