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 ...

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 ...

You can take any particle in the Universe and isolate it from everything else, yet there are some properties that can never be taken away. These are intrinsic, physical properties of the particle ...

This orbital angular momentum has recently gained a lot of attention, as researchers hope to encode information into it and thus either enhance the capacity of fiber optical communication systems, or ...

In this video, we explain the conservation of angular momentum in AP Physics 1, showing why angular momentum remains constant and how it applies to rotating systems. You’ll see clear examples that ...

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

Discover how the Earth started spinning, the impact of the Theia collision, and how the Moon's gravity is gradually slowing ...

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 ...

It’s a question I’m sure was keeping you up at night: can you make an object spin with a sound wave? The answer, generally speaking, used to be no. Now, though, mechanical engineers have taken a look ...
