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 principle ...

This Chapter 10 summary covers the key concepts of rotational motion and angular momentum in physics. The video explains torque, rotational kinematics, moment of inertia, and conservation of angular ...

Watching, modeling and even playing winter sports help students internalize physics concepts, including acceleration, ...

Let me get rid of the θ and r3 terms where: This gives an angular momentum of: The same as before. So, although the person is moving in a straight line the angular momentum (about that rotation point) ...

The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a ...

Fig. 1 The measured time-resolved KER spectrum (A) and the measured photoion momentum distributions at different delays (B) of O2 molecules. The coupled electronic and nuclear motions within a single ...

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 ...

Because of Earth's dynamic climate, winds and atmospheric pressure systems experience constant change. These fluctuations may affect how our planet rotates on its axis, according to NASA-funded ...
