Time independent acceleration equation?

  1. Jul 11, 2010 #1

    Is this differential equation valid for time independent acceleration"

    a = dV/dt = dV/ (V dx) = ( dV / dx ) * (1/V) ?

    It's not quite clear what you're doing here. dV/dt has units of acceleration, while dV/(V dx) has units of 1/length. So your equation isn't valid.

    Perhaps you're thinking of dV/dx = (1/V)dV/dt ?

    Oh ! my obvious fault: a = dV / dt = dV/ (dx / V) = V dV/dx .
