for example, with an elevator not moving you have weight down and tension up. but lets say it starts moving up...being on that elevator would make it FEEL heavier, correct? but the elevator is moving up so isnt the force going up? im trying to make a free body diagram to show a persons new weight on an elevator with say a = 1 m/s^2 going up (or any number). i know the answer is weight = (mass)(acceleration) where a = 9.8 + 1 (due to elevator) but how do you show it and explain it? thanks.
