I love using seemingly random data to figure out stuff I wouldn't otherwise know. You can do this with all kinds of things, but in this example, I use video that I recorded from an airplane to figure ...

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 ...

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 ...
