Hi All, I’ve uploaded a first set of problems onto the Physics playlist. The set first demonstrates how I do unit conversions – an oversight on my part, should have done them before – and then five problems calculation frictional forces or coefficients of static or kinetic friction. Set two will be along shortly. You can find set 1 here.
Friction will be a familiar concept … everyone has rubbed their hands together during the winter to warm them … force makes the hands move, speed is related to kinetic energy, energy becomes heat … is that how that works? … but the fun part comes when you look at the action on the molecular level. Question, grasshopper … are your hands really touching?
Enjoy the set, let me know if you ave questions. Don’t forget to click the “Follow” link to keep updated.
