Let me get rid of the θ and r3 terms where: This gives an angular momentum of: The same as before. So, although the person is moving in a straight line the angular momentum (about that rotation point) ...
In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...
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 ...
