WebExample - Force and Power to Lift an Elevator. An elevator with mass 2000 kg including passengers are moved from level 0 m to level 15 m. The force required to move the elevator at constant speed can be calculated as. F c = (2000 kg) (9.81 m/s 2) = 19820 N. The power required to move the elevator between the levels in 20 s can be calculated as Web1 de ago. de 2024 · This requires an increased normal force. When the elevator is accelerating downwards, it does not need to oppose gravity as much and so the normal force decreases to provide a net downward force from gravity. No changing mass is needed.
