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 ...

For the angular velocity, the radius changes as well as the component of the velocity that is going perpendicular to this radius (that part that is like it is moving in a circle). For the moment of ...

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 ...

Introduction The bottle-flipping craze might be dying down, but it isn’t too late to investigate the physics of this internet sensation. Even if you’ve never heard of it, give this project a try—not ...

Diving is among the most popular spectator events in the Olympics, a graceful sport that combines elements of gymnastics and dancing. It’s also an excellent example of physics in action. Let’s look at ...

ABSTRACT The technology to estimate engine load using the amplitude of crankshaft angular velocity variation during a cycle, which is referred to as “Δω (delta omega)”, in a four-stroke ...
