    Motion?

    Hi,

    When a hammer collides with a pile, the pile is driven into the ground, so we have the motion of the pile into the ground.

    Please tell me if "motion" is correctly used!

    Yes, it's used correctly. "Motion" is usually used for things that move by themselves though. But the pile certainly moves through the ground, so "motion" is strictly OK.
    I would write, "so we have the forcing of the pile into the ground", or something similar; but if you're concentrating on the movement/motion, it's fine.
