to press all of the buttons in an elevator‚ and gauge the responses of the other passengers. The objective was to see how people would react or respond to this odd act. We believed that people would become irritated and say something to us or other passengers. If we press every button on an elevator‚ then bystanders will be visibly uncomfortable with this deviation from the cultural norm. II. Methods For our experiment‚ we chose to press every button in an elevator. To begin‚ we started on the main

was an elevator that functioned as well as having to rain inside the elevator as well. The first thing that had to be done was that the crew had to figure out how an elevator worked While being able to build it in the time limit that we had. Another problem that was added to making the elevator was that it had to be able to be taken apart so it could be transported to other schools along with the rest of the set. It was decided that a belt and pulley system would be used to make the elevator operational

Apparent Weight: Person on Scale in Elevator A person with mass‚ m‚ who is located at or near the surface of the Earth will always have some weight W=mg. When a person stands on a scale‚ the reading (the number of pounds or newtons) on the scale is actually the Normal Force that the scale exerts back towards the person to support the person’s weight. (Note that the person and the scale are stationary relative to each other‚ in other words they are always in contact with each other‚ so they always
