Today in 1960, France Sahara desert. However, in our Physics class, we started class by finishing the video, and then we changed gears into our lab manual. We worked on pages 131 onwards, which dealt with roller coasters. We discussed multiple errors in various structures and methods to prevent those errors, followed by a reading and questions to accompany it. There were a few math problems related to that which we worked on in the end. We were running out of time so Coats-Haan took over and quickly finished the problem since we were running out of time. Homework is to finish number 10 and 11 from that assignment. We had nothing to turn in from the weekend as we spend Friday watching the roller coaster video. However, in our folders we got our test review and lab report back. Question of the Day: the normal force at the top of a roller coaster, if the passengers are just at the verge of falling off, is equal to the gravitational force, and thus F=mg.
