Hey sorry I just saw this message. Actually there is no change in the gravitational force! It's the contact force that changes - if the contact force from the weighing scale pushing the man upwards exceeds the weight, the man (and the lift) are accelerating upwards; if the contact force from the weighing scale pushing the man upwards is less than the weight, the man (and the lift) are accelerating downwards. An example of a downward acceleration is an object slowing down as it is moving upwards.

For every action there is an equal and opposite reaction? You go up, the resting body is affected by an extrinsic force and the weight changes due to gravitational changes.

yeah,in your bare feet standing on a weighing scale.
most likely they'll just wait for the next one.

Newton's third law of reaction force applies =)

cher, what would have happened if someone actually came into the same lift as you when you were doing that?
lol
eh, explain in class leh...
