Work and Power Calculator

One horsepower is equal to 735.5 watts, or joules per second. So, if work is done at one horsepower for 1 second, that's equal to 735.5 joules.

Work as force * distance -- what about mass? [closed]

If you bring in "force to a mass over a time" you do not compute work; in that case you solve an equation of motion: md→xdt2=→F(x). Another ...
