Dear Thomas

These all look good to me. I agree that "displacement" conveys the idea of
moving from A to B. A displacement would be extensive in time, and the time
bounds would record the two measurement instants between which the displacement
occurred. By contrast, a velocity is intensive in time.

Best wishes
