The project is an opportunity to explore one bit of physics from the semester in a little more depth.
Instead of a general book report type thing, the goal of this assignment is simply to create some visual representation of something we've covered in the class (or something else from Classical Mechanics, like in the extra chapters at the end of the book that we didn't have time to get to.) That means, take some analytical physics (i.e. equations/math) and turn them into something visual. Simplest case, make a plot! Explain a bit of the physics you are dealing with, but I don't need a biography of Newton or anything. You don't have to go out in the world and measure something (but you could). Just something involving an analytical function is fine. (but try to make it at the level of this course PHYS 35100, not just intro physics)
Your report should be typed (in latex preferably) with some math, and contain a graph (i.e. plot of something) and maybe a figure of some kind.
These are some examples of similar projects that I prepared for PHYS 20700 (and are at that level of physics, not 35100 level). They all involved actually measuring something in the world, which isn't a necessity for this project, but it should help give the basic idea.
