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 ...

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 ...

A slower peak angular velocity during turning while walking could help in tracking motor progression in the prediagnostic phase of Parkinson's disease (PD) and predicting an elevated risk in older ...
