Fish koozies and Bart’s Comet: Pre-class overheads (November 4 – 8)

(This post is part of an ongoing, semester long series. Each week, as a lecture TA in Physics 100, I choose a pre-class overhead for each of the two lectures I help out in. I attempt to choose images that connect to the current material and that are fun and possibly provocative. Here, I keep […]

Simpsons and prone bikes: Pre-class overheads (October 21 – 25)

This week, we continued talking about conservation of energy and the work-energy theorem and began to talk about power. Something I did not appreciate when I first learned these concepts was how power-ful they really are.┬áSome of the problems we did in lecture include estimating the fuel efficiency of a car and estimating how much […]

Roller coasters and Red Bull Stratos: Pre-class overheads (October 14 – 18)

This week in Physics 100, we began talking about mechanical energy. For our first class this week, I went back to what I feel is one of the canonical examples of mechanical energy conservation: the roller coaster. This is something I explicitly remember as being the topic of energy problems in my high school physics […]
