In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

In the sport of hammer throw athletes need to make the most out of many physics rules in order to achieve the best results. Angular speed and throwing precision must be well calibrated to send the ...
