What is the effect of gravity on a person in elevator?

The effect of gravity on a person in an elevator is exactly the same as it is anywhere

else. The person and the Earth are attracted toward each other by equal forces whose

strength depends on the product of their masses and the distance between their centers.

The person feels heavier when he starts a trip going up or finishes one going down, and

he feels lighter when he starts a trip going down or finishes one going up. But that's the

effect of the elevator, not the effect of gravity.
