Force and PE

  1. Dec 18, 2004 #1
    does the integration of Force equal negative potential energy?

    [tex]\int{F}={-U}[/tex]

    Also, what is the difference between [tex]\oint[/tex] and [tex]\int[/tex]?

    Yeah, it should seeing as F = - dU/dx.

    The integral sign with a circle is an integral around a closed loop/surface I think, whereas the normal integral sign isn't.

    so: W’=F=-dPE/dt

    The [tex]\oint[/tex] is often used for a curve integral (whether or not the curve is looped (closed) or not).
