Elevator Simulation Lab

To begin… Read the entire lab sheet before continuing with this virtual lab so that you will be familiar with the procedures used. The following slides take you through the data that you would have seen if you had performed the lab.

Your weight on a non-moving elevator scale 150 lb

Your apparent weight right when the elevator starts and is accelerating upwards. scale 161 lb

Your apparent weight while the elevator is in the middle of its path travelling at constant speed. scale 150 lb

Your apparent weight while the elevator slows to a stop. scale 141 lb

Your apparent weight while the elevator begins to move downward. scale 141 lb

Your apparent weight while the elevator is in the middle of its path at constant speed. scale 150 lb

Your apparent weight while the elevator slows to a stop. scale 161 lb

That’s it!!! You will probably need some help with this to understand the forces involved. Come in for tutoring or if you would like to try it on your own, check out the following site for an explanation of the forces involved. http://dallaswinwin.com/Newtons_Laws/weight_elevator.htm Good luck!!!
