What is it? Power is the rate or speed at which work is done. The more power something has, the faster it can complete a specific task. We measure the power of machines in units such as the Watt or horsepower. Give me an example! Have you ever overheard people talking about the difference in horsepower between two cars? Horsepower is simply a standard measurement used to rate the amount of work an automobile engine (or any machine) can do in a specific time. An engine that is rated at 200 horsepower has 200 times the power to pull a specific load at a specific speed as an average horse. The 200 horsepower engine also generates twice the power of a 100 horsepower engine, so it does twice as much work in a given amount of time ... which makes it faster. Therefore, the higher the horsepower rating an engine has, the faster a vehicle will move. |
