1. The problem statement, all variables and given/known data The PDF graph shows the g-force values of a roller coaster at specific times during the ride. The normal g-force value during this assignment is -1 because the acceleration due to gravity on earth is -10 m/s^2. We have to assign each time value from the PDF graph to certain points on the roller coaster, but that's not really my problem. 2. Relevant equations 3. The attempt at a solution Going my teacher's logic for the g-values, a bigger negative g-force value means you feel heaver, while a less negative g-force value/positive g-force value means you feel lighter. This contradicts some research I've done, but that's mainly because we use -1 as the standard value instead of 1. However, according to the PDF file, going up the incline (the first hill), you feel lighter, while going down the incline, you feel heavier. Isn't this opposite of what should be happening? Am I missing something here? I've attached the graph and the picture of the roller coaster.
