How can power be defined in terms of work?

• A. Work multiplied by time
• B. Work divided by distance
• C. Work divided by time
• D. Work minus time

Answer: (C)

Power is defined as the rate at which work is done or the amount of work done per unit of time. This definition can be represented mathematically as power equals work divided by time. When you perform a certain amount of work, power quantifies how quickly that work is accomplished. For example, if you lift a weight, the amount of work done is based on the weight lifted and the height it is lifted. Power gives insight into how fast you can complete that task; if you lift the weight quickly, you are demonstrating higher power output compared to lifting it slowly. This definition highlights the relationship between the work done and the time taken to do that work, making it clear how efficiently energy is being utilized in a process. This concept is widely applicable across various fields, including physics and engineering, where understanding the efficiency and rate of work is crucial.
