In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy ...

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 ...

What Is Angular Momentum? Angular momentum is a measure of rotational motion. We can calculate it as the vector product of an object's position and its linear motion.

Key concepts Physics Angular momentum Tension Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more ...

Photons can have half-integer values of angular momentum when they are confined to fewer than three dimensions. That is the conclusion of physicists in Ireland, who have revived an experiment first ...

Where does the angular momentum go? To find the lost angular momentum, Peter Baum and members of his team at Konstanz began by magnetizing nickel crystals in a specific direction, then demagnetizing ...

Angular momentum is basically momentum with a rotational motion — an object’s angular velocity (how fast it’s spinning) multiplied by its moment of inertia.

Quantum technologies, devices that work by leveraging quantum mechanical effects, could outperform classical technologies in ...

In order to talk about whether a fidget spinner in space will ever stop, we have to dig into why they stop on Earth, when fundamental physics says their angular momentum should last forever.

From a basic physics viewpoint, our results help to resolve key questions such as the conservation of angular momentum in highly nonlinear light–matter interactions, and the disentanglement and ...
