This resource includes an interactive simulation of a person in an elevator and can simulate riding upward or downward two different distances. There is a free body diagram of the person next to the image of the elevator and as the elevator moves the free body diagram changes to reflect the changing forces. The person in the elevator has a speech bubble in which they comment on how they feel during the ride. The interactive is simplistic in its controls and options for the student, but focuses well on what is happening to the forces during the ride. It is easy to repeat and compare longer rides with shorter rides, or upward rides with downward rides. There is accompanying text to assist the student with understanding as well as a few teacher notes about the misunderstandings that students may have about this situation.
