The very first textbook chapter I edited (way back in 2008!) was on work and machines, so I have a soft spot for the topic. It’s also the focus of the “Science Playground” exhibit at the science museum I work for (and no, I will never, ever tire of the phrase “the science museum I work for”.)
There are lots of things to push and pull, and it’s a ton of fun interacting with guests who are lifting 550 pounds for the first time. It’s made me nostalgic for my textbook days, so I thought I’d summarize some of the key concepts and formulas here.
