Question

The diagram shows a section through the station.
The passengers who use the station are carried from platform level to street level in a lift.

Explain why these passengers gain gravitational potential energy in the lift, even when they are below ground.

Answer 1

Answer:

where is the diagram bro ???

Answer 2

Answer:

GPE = mgh; when using this equation, h refers to the change in height. Passengers have moved to a higher point when they are carried from platform level to street level. Since gravitational force still acts underground, work is done on the passengers against gravity to lift them to a higher point.
