Ask any engineer what the velocity of a point on a rigidbody is, and he will correctly say that it is the timerate of change of a linear position vector. Ask anyengineer what angular velocity is, and ...

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 ...

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 ...
