1. The lift is said to be moving with net upward acceleration in two possible conditions:
- when the lift just starts moving upwards or
- is about to stop at a lower floor during its downward motion.
2. As the net acceleration is upwards, the upward force must be greater.
∴ F = ma = N – mg
∴ N = mg + ma
∴ N > mg
3. Thus, for a passenger inside this lift, his apparent weight is more than his actual weight when the lift was not accelerated.
