I was a bit disappointed to see the differences between "algebra based physics" in high school and "Calc based physics" in college. It wasn't a whole lot more than "now rather than giving you formulas, do an integral to go from acceleration to speed, or speed to position".

It did feel good to see a practical use for the calculus I had learned, much more so than determining how much the surface area changed after adding a layer of paint 0.01" thick to a tank.
