In physics class on Friday we watched a very interesting video on roller coasters. Before the video we were asked to fill out the before true/false questions on Extreme Machines Roller Coasters found on page 129 of your lab manual. The video took up the entire class time and Coats-Haan promised us that the video was rated PG, but I am not sure on that one. It was also hard not to laugh during the video, especially with the contagious laughter of Alexis. Overall it was a very relaxing class and if you did not turn in the worksheet on the video on Friday then you can turn it in on Monday, otherwise there is no homework due on Monday.
Question of the Day: Explain the g forces you experience on a roller coaster- well the g forces on roller coasters usually vary between +4 and -1/2. The more positive g's are experienced at the bottom of a drop.When accelerating downward you experience less positive g's which make you feel weightless and when accelerating up a steep hill you will feel heavier than normal because of the extra positive g's.
