A simple question about gravity.

    Is the length of time for which an object is falling directly proportional to the force it hits the ground with?

    The speed of a falling object is proportional to time (assuming no air resistance) V=u+gt

    The force it hits the ground with depends on how quickly it stops.
    But if we assume the stopping time is the same then F=ma and a (deceleration) is speed/stopping time

    So yes.

    In the context of things falling close to the Earth's surface, yes.
