In this video, we determine the maximum angular speed a coin can have on a rotating turntable without slipping. By analyzing static friction and centripetal force, you’ll learn how rotational dynamics ...

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

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 ...
