Many people don't know too much about angular momentum—and that's fine. But what about figure skaters? Whether they understand the concept of angular momentum doesn't matter but they use it in one of ...

While weight and mass might affect how fast an objects falls, moment of inertia is the key to speed today! Much like a figure skater pulling their limbs in to speed up a spin, the more mass an object ...

Since energy is conserved (the gravitational force is conservative), we can use the work/energy equation to determine the speed of the satellite as a function of the distance R from O to P. Since the ...

Light beams with a helical phase-front possess orbital angular momentum along their direction of propagation in addition to the spin angular momentum that describes their polarisation. Until recently, ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

It's almost always the last topic in the first semester of introductory physics—angular momentum. Best for last, or something? I've used this concept to describe everything from fidget spinners to ...

Electronics traditionally rely on harnessing the electron's charge, but researchers are now exploring the possibility of harnessing its other intrinsic properties. In a Nature Communications study, ...

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 ...
