Question

a man is moving from first floor to ground floor in a lift what happens to his weight

Answer 1

At the beginning,

When the elevator is accelerating downward,

• It reaches a steady speed and the weight of the person becomes normal
• It starts decelerating as the life moves downwards  

Inference:

• Weigh is less at the beginning when the elevator moves down
• Weight is more at the end when the elevator moves down

Hence, his weight is less at the beginning of the trip down and more when the lift reached the ground floor.
