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 ...

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 ...

For the angular momentum principle, the change in angular momentum is equal to the net torque. If the system is the bullet and the merry go round, the net torque is zero.

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.

A research team succeeds in solving a decade-old physical puzzle: the question of the fate of angular momentum during the ultrafast demagnetization of nickel crystals by laser light.

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