Why does a person feel weightless inside a freely falling lift ?

  • A.Gravity ceases to act inside the lift
  • B.The lift and the person fall with the same acceleration, so the floor exerts no reaction
  • C.The air pressure inside the lift falls
  • D.The person’s mass becomes zero

Answer: C

Correct answer: The lift and the person fall with the same acceleration, so the floor exerts no reaction

Weight is felt through the normal reaction of the floor, and when both fall together at \(g\) that reaction drops to zero. Gravity continues to act throughout, which is precisely why they are falling.
