2. Spin quantum number - Wikipedia

   en.wikipedia.org/wiki/Spin_quantum_number

   [1] [2] The value of m s is the component of spin angular momentum, in units of the reduced Planck constant ħ, parallel to a given direction (conventionally labelled the z –axis). It can take values ranging from + s to − s in integer increments. For an electron, m s can be either ⁠+ + 1 / 2 ⁠ or ⁠− + 1 / 2 ⁠.

3. Equations of motion - Wikipedia

   en.wikipedia.org/wiki/Equations_of_motion

   There are two main descriptions of motion: dynamics and kinematics.Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations.

4. Euler's laws of motion - Wikipedia

   en.wikipedia.org/wiki/Euler's_laws_of_motion

   Euler's second law states that the rate of change of angular momentum L about a point that is fixed in an inertial reference frame (often the center of mass of the body), is equal to the sum of the external moments of force acting on that body M about that point: [1] [4] [5]

5. Spin-1/2 - Wikipedia

   en.wikipedia.org/wiki/Spin-1/2

   Heuristic depiction of spin angular momentum cones for a spin-⁠ 1 / 2 ⁠ particle. Spin-⁠ 1 / 2 ⁠ objects are all fermions (a fact explained by the spin–statistics theorem) and satisfy the Pauli exclusion principle. Spin-⁠ 1 / 2 ⁠ particles can have a permanent magnetic moment along the direction of their spin, and this magnetic ...

6. 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.

7. Spin (physics) - Wikipedia

   en.wikipedia.org/wiki/Spin_(physics)

   Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [1] [2]: 183–184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory.

9. Quantum state - Wikipedia

   en.wikipedia.org/wiki/Quantum_state

   For example, it is possible to observe a particle with a momentum of 1 kg⋅m/s if and only if one of the eigenvalues of the momentum operator is 1 kg⋅m/s. The corresponding eigenvector (which physicists call an eigenstate ) with eigenvalue 1 kg⋅m/s would be a quantum state with a definite, well-defined value of momentum of 1 kg⋅m/s, with ...
