Follow me! Doodle Science teaches you high school physics in a less boring way in almost no time! Script: Work is the amount of energy transferred when a force moves something. For example when you carry something upstairs or a lift a heavy object, work is being done. You can calculate the amount of work being done by knowing the force applied and the distance the object has travelled. The work is measured in Joules; the force in Newton's and the distance in meters. If this guy pushes this box with a force of 300N and he moves it by 2m, the work done is 600J. Lets just say it took him 20 seconds to do it, but there is another guy who pushed a box in 10 seconds with the same force and by the same distance. It's tempting to say that the second guy did more work, but the time is irrelevant when it comes to the work done. So cheer up, you can both have medals. The difference is the power at which they pushed the box. You can calculate the power in Watts by dividing the work done, by the time in seconds. In this case the first guy pushed the box with a power of 30 Watts and the other guy pushed it with a power of 60 Watts, who do you think's stronger?\n
