Everyone should probably know that I'm obsessed with both physics and smart phones. If I can use my phone for a physics experiment, I'm good to go. That's exactly what I am going to do right now—use ...

Ask any engineer what the velocity of a point on a rigid body is, and they will correctly say that it's the time rate of change of a linear position vector. Ask any engineer what angular velocity is, ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

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 ...

Abstract: This paper addresses the attitude tracking control problem of liquid-filled spacecraft in the presence of angular velocity constraints and limited control torque. Significant challenges ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
