Speedy Spinning Spheres! Using spheres, cylinders, and straws, the Crew and Dr. Rob learn about inertia, velocity, and conservation of energy due to angular momentum. STEM Challenge: Angular Momentum ...

A new experiment confirms that angular momentum conservation holds even when a single photon is split into two.

In a closed physical system, the sum of all angular momentum remains constant – says an important physical law of conservation. Angular momentum does not necessarily need to involve "real" bodily ...

Physics is a natural science that, compared to others, is less popular among the general population, both adults & children. However, awareness of the presence of physics in every corner of our ...

Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...

Recently, National Science Review published online the research results on three-dimensionally oriented orbital angular momentum of light from Professor Qiwen Zhan's team at the University of Shanghai ...

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 ...

China’s massive Three Gorges Dam has reportedly caused a subtle but measurable shift in the Earth’s axis and a slight ...

Earth is steadily spinning like a top, even if we can't see, touch, hear or feel it. So, what would happen if Earth were to abruptly stop rotating? If the spinning were to stop, the angular momentum ...

When a magnetic material like nickel is zapped with an incredibly short laser pulse, it loses its magnetism almost instantly within femtoseconds, or a millionth of a billionth of a second. But physics ...

Water waves can be used to visualize fundamental concepts, such as spin angular momentum, that arise in relativistic field theory, RIKEN physicists have shown. This will help to provide new insights ...
