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 ...

There is the work-energy principle, the momentum ... angular momentum of the Earth plus the angular momentum of the person. That's about it. I essentially know all the values to put into that ...

This happens, thanks to a physics concept known as the “conservation of angular momentum.” But how can you try it out if you don’t have any ice skates around? Find out in this simple ...

The uncertainty principle states that we cannot know the state of a system with arbitrary precision. Now the uncertainty relation between angular momentum and position has been measured in an ...

Twisted light: self-torque could be used to manipulate molecules. (Courtesy: iStock/VikaSuh) Physicists in Spain and the US have shown that the orbital angular momentum, or twistedness, of light can ...

A study examines angular momentum constraints on the formation and orbital evolution of the Moon. Proposed scenarios for the Moon's formation typically involve a giant impact that would have left ...
