Homework Help: 20 Hp or 10 Hpwhich one does more work?

  1. Dec 13, 2008 #1
    I know the 20 HP does more work, but why?

    Is there a conversion unit where I convert 20 HP to Joules?

    Power is defined as the rate of doing work, thus the greater the power, the greater the work done per unit time.

    Power is a measurement of work over time J/s in (or watts) in the metric system.
    1 J/s = 1 Watt and 746 W = 1 hp
