    A J = Ns not N/s

    One Joule of energy is one Newton of force applied for 1 second.

      Muphry’s law at work - for both of us, actually. I looked it up (since with Ns the units no longer worked out between E = mc² and F = ma), and a joule is actually a Nm, a Newton-meter. And with that the units do work out correctly on both equations.

        That is really unintuative, torque is Nm…how can energy also be Nm.

        But then I look at it and J = Ws = N(m/s)s = Nm
