Physics 211 Lecture 4, Slide 3 I would appreciate some discussion on the ties between calculus and the three laws. I don't quite understand how the change of momentum relates to net force and acceleration. im thinkin there is nothin to worry about for this business. its not a situation. I felt very confident during most of the time while doing the prelecture and preflight, you can go over whatever you want as far as I'm concerned. Why (in physics terms) wouldn't an object like a wall move according to Newton's Third Law if it does not have balanced forces on it (net force =/=0, so shouldn't it accelerate per Newton's First Law? Stuff you asked about: How does net force differ from other forces? Also, in relation to centripetal motion, in which directions are acceleration, momentum, and velocity. why the acceleration of the car is towards the center of the circle, yet the car's velocity is pointing directly forward from the car at any point in time. I knew all of these surprisingly well. Or at least I think I do. Does Mats class score higher than Stelzers? Has it been tested before in the past? You always ask us about ourselves and our problems, I would like to know a little about you.

Physics 211 Lecture 4, Slide 4 This coming weekend is a long one due to Labor day and Loomis will be locked. This means we can’t have the usual office hours on Sunday & Monday (sorry). To make up for this we are making the following changes to Homework 2: 1) Extending the first deadline to Wednesday morning (Sept 8). 2) Extending the second (late) deadline to Sept 15 3) Changing the “late credit” from 80% to 90%.
