This content defines angular momentum (ℓ) for a particle as the cross product of its position vector (r) and linear momentum (p), i.e., ℓ=r×p=m(r×v). It clarifies that angular momentum is a vector quantity defined with respect to a...

Dive into Unit 6 of AP Physics 1: Energy and Momentum of Rotating Systems! This video covers rotational kinetic energy, torque, work, angular momentum, rolling without slipping, and conservation laws. Watch as we connect linear and...

How a black hole's ergosphere may help us go faster than the speed of light.

The Stern-Gerlach experiment, which took place in 1922, was the most important proof that electrons have spin and that they have a spin quantum number. A stream of silver atoms was sent through an experiment using a magnetic field...

Characterised by the symbol 𝑙l, the azimuthal quantum number is a fundamental parameter in quantum mechanics that describes the angular momentum and form of an electron's orbital within an atom. The integer values it accepts range from...

The magnetic quantum number  abbreviated as m  represents the orbital orientation of an electron in a given energy level and sublevel. Here's a thorough rundown:

In 1913, Niels Bohr proposed an atomic model that dramatically altered our comprehension of atomic structure by establishing a novel framework for describing the arrangement and behaviour of electrons within an atom....

A pulsing black hole in the centre of a distant galaxy sheds light on black hole and galaxy formation. How fast are black holes rotating and how does that rotation change over its life-span?

Niels Bohr's model of the atom introduced the idea of quantised orbits for electrons. In these, electrons occupy stable energy levels and either give off or take in photons when they move between these levels. This model was able to...

How the universe works: a black hole is surprisingly hard to fall into.

Betelguese, a red super-giant star, could be breaking the laws of physics.

In this video, we explore the Jana Bekoff Effect (or the Intermediate Axis Theorem), which involves the surprising flipping motion of objects like a wingnut in space. This phenomenon, first observed by cosmonaut Vladimir Jana Bekoff in...

Quantum entanglement is a physical resource, like energy, that is possible between quantum systems. When a coin spins on a flat surface, its in a state of superposition between its two faceshead and tails. Similarly, electrons in their...

Join us as we delve into the physics that make figure skating possible. From pirouettes to acrobatic lifts, learn how skaters like Sarah Abitbol utilize principles such as angular momentum and the gyroscopic effect to perform stunning...

Astrophysicist Scott Tremaine, Institute for Advanced Study, describes the many open scientific questions associated with Saturn and its rings, describing what we know, what we don’t know, and why we know there’s a problem with some of...

In this representation I discuss the main principles of quantum mechanics behind the quantum computer. and How to build a device that can manipulate the energy operator of the Schrodinger Equation for an electron to change its spin...

This is a review of all of the dimensions used in AP Physics C - Mechanics. Okay, maybe it doesn't cover some of the basic dimensions, however, if you don't know that linear velocity is in furlongs per fortnight, then I probably can't...
