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 ...

Consider the rotor of a gyroscope. The rotor is attached to a frame that is rotating about a fixed vertical axes with a constant rate of ω 1, and with the rotor rotating relative to that frame at a ...

The University of Virginia is investigating the use of a magnetohydrodynamic (MHD) angular rate sensor to measure head angular acceleration in impact testing. Output from the sensor, which measures ...

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 ...
