Hey all, I'm taking Physics Unit 1: Physics on the Go in a few more days, and I want some notes on the elevator system, where if the reading on the weighing scale in the elevator increases, is it accelerating upwards or downwards or constant velocity and stuff like that? Sorry, but my teacher didn't really go into it so I'm a bit lost. Anyone got a simple but clear answer about why it's so and so? Also, any tips on application questions? My lecturer mostly gave us notes and taught the various concepts but my pals and I are still a bit blur on certain application questions, as in, we're not sure how to relate a particular concept to the question. Thanks much.
