    Is Motion a scalar or vector or neither?

    Motion is not something even quantifiable. You can say a system has a higher velocity, or more momentum or more kinetic energy, but not more motion.

    excuse me, what do you mean by quantifiable?

    One definition of motion I have seen is a time-dependent map from phase space to phase space. Which is quite a bit more complex than scalar vs vector.

    'quantifiable' = capable of having a number, or quantity, assigned to it.
