  2. Orbital ring - Wikipedia

    en.wikipedia.org/wiki/Orbital_ring

    An orbital ring is a concept of an artificial ring placed around a body and set rotating at such a rate that the apparent centrifugal force is large enough to counteract the force of gravity. For the Earth , the required speed is on the order of 10 km/sec, compared to a typical low Earth orbit velocity of 8 km/sec.

  3. Particle in a ring - Wikipedia

    en.wikipedia.org/wiki/Particle_in_a_ring

    The case of a particle in a one-dimensional ring is an instructive example when studying the quantization of angular momentum for, say, an electron orbiting the nucleus. The azimuthal wave functions in that case are identical to the energy eigenfunctions of the particle on a ring.

    A quasiparticle resulting from electron spin–orbital separation: Oscillon: A soliton-like single wave in vibrating media Phason: Vibrational modes in a quasicrystal associated with atomic rearrangements Phoniton: A theoretical quasiparticle which is a hybridization of a localized, long-living phonon and a matter excitation [10] Phonon

  5. Megastructure - Wikipedia

    en.wikipedia.org/wiki/Megastructure

    An orbital ring is a dynamically elevated ring placed around the Earth that rotates at an angular rate that is faster than orbital velocity at that altitude, stationary platforms can be supported by the excess centripetal acceleration of the super-orbiting ring (similar in principle to a Launch loop), and ground-tethers can be supported from ...

    en.wikipedia.org/wiki/Glossary_of_physics

    A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.

    3) are considered examples of a two π electron system, which are stabilized relative to the open system, despite the angle strain imposed by the 60° bond angles. [11] [12] Planar ring molecules with 4n π electrons do not obey Hückel's rule, and theory predicts that they are less stable and have triplet ground states with two unpaired ...

  8. Three-body problem - Wikipedia

    en.wikipedia.org/wiki/Three-body_problem

    In physics, specifically classical mechanics, the three-body problem is to take the initial positions and velocities (or momenta) of three point masses that orbit each other in space and calculate their subsequent trajectories using Newton's laws of motion and Newton's law of universal gravitation.

  9. Orbital motion (quantum) - Wikipedia

    en.wikipedia.org/wiki/Orbital_motion_(quantum)

    Quantum orbital motion involves the quantum mechanical motion of rigid particles (such as electrons) about some other mass, or about themselves.In classical mechanics, an object's orbital motion is characterized by its orbital angular momentum (the angular momentum about the axis of rotation) and spin angular momentum, which is the object's angular momentum about its own center of mass.
