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 ...

Can we create artificial gravity, or is it still science fiction? In this video, we break the problem down using real physics ...

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 ...

Diving has gotten a lot of strange attention this year, thanks to a lack of filtration chemicals that caused the water to turn from a pristine blue to a worrisome green, which Olympic officials are ...
