"The force vector of motion is equal to the motive force vector."

He defines both of these terms in the previous two paragraphs, but his definition of "motive force vector" is rather convoluted. I was wondering if this law could be expressed more simply, or at least using different terminology like four-acceleration, four-momentum, proper time, etc.

Thanks.
