There are quite a few physics textbooks that actually ask about work done by friction. The first book I grabbed had an example that was something like this: Jake pulls a box with a mass of 22 kg.

Jaqueline Krim, who heads a nanotribology lab at North Carolina State University, says that just two basic laws about friction, wedged into an introductory physics course, comprised “almost 100% ...

The ratio of the fibre dimensions and the friction coefficient, which they call the “Hercules number” determines whether a yarn forms, and Crassous is confident that this bolsters their results, ...

Science presenter Jon Chase explains friction. He describes how friction opposes or prevents motion, and demonstrates the force in action with an experiment involving two interleaved books ...

The smoke you see rising from a fire results from incomplete combustion. Work smarter, not harder. Understanding the physics of fire by friction and the different variables involved can make a big ...

The story takes place in an area of physics that has been long-neglected: friction. Everyone knows it exists, engineers have a bunch of empirical formulas to calculate it, but no one gave much ...
