    The person's weight is (mass) x (gravity) = (75 kg) x (9.8 m/s²) = 735 newtons.

    When the elevator is at rest, or moving up or down at a constant speed,

    the scale reads 735 newtons.

    When the elevator starts moving upward from rest, or moving down

    but getting slower, the scale reads a higher number of newtons.

    When the elevator starts moving downward from rest, or moving up

    but getting slower, the scale reads a smaller number of newtons.

    A properly marked scale will never read anything in kilograms,

    because 'kilogram' is a unit of mass, not force or weight.
