eSaral Class 11 Physics Motion in a Lift What is Apparent Weight and Why Does It Change in a Lift? Your actual weight is the gravitational force Earth exerts on you: $W = Mg$ This never changes as long as your mass and $g$ remain constant. Your apparent weight, however, is the force you feel the normal reaction $N$ that the floor of the lift pushes back on you. When the lift is stationary or moving at constant velocity, $N = Mg$, so apparent weight equals actual weight. The moment the lift accel...
