Elevator problem

  1. Oct 3, 2009 #1
    If the elevator is accelerating downward, can you have a negative normal force being exerted on an elevator floor by a person? since the floor exerts an upward normal force on the person.

    Hi devinmacd33! Welcome to PF! :smile:

    You can't have a negative reaction force … when the reaction force becomes zero, contact is lost. :wink:

    (or do you mean is the person's force on the elevator floor downward? yes, whether the elevator is accelerating or not)
