  2. Physics - Wikipedia

    en.wikipedia.org/wiki/Physics

    Physics is also called "the fundamental science" because all branches of natural science including chemistry, astronomy, geology, and biology are constrained by laws of physics. [47] Similarly, chemistry is often called the central science because of its role in linking the physical sciences.

  3. Lecture Notes in Physics - Wikipedia

    en.wikipedia.org/wiki/Lecture_Notes_in_Physics

    Lecture Notes in Physics (LNP) is a book series published by Springer Science+Business Media in the field of physics, including articles related to both research and teaching. It was established in 1969.

  4. Physical chemistry - Wikipedia

    en.wikipedia.org/wiki/Physical_chemistry

    Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a supra-molecular science, as the majority of the principles on which it was founded relate to the bulk rather than the molecular or atomic structure alone (for example, chemical equilibrium and colloids).

  5. Partition function (statistical mechanics) - Wikipedia

    en.wikipedia.org/wiki/Partition_function...

    In physics, a partition function describes the statistical properties of a system in thermodynamic equilibrium. [citation needed] Partition functions are functions of the thermodynamic state variables, such as the temperature and volume.

  6. Jerk (physics) - Wikipedia

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

    When converted to an equivalent system of three ordinary first-order non-linear differential equations, jerk equations are the minimal setting for solutions showing chaotic behaviour. This condition generates mathematical interest in jerk systems. Systems involving fourth-order derivatives or higher are accordingly called hyperjerk systems. [1]

  7. Shear force - Wikipedia

    area of the bar in mm 2 = (12.5 2)(π) ≈ 490.8 mm 2 0.8 kN/mm 2 × 490.8 mm 2 = 392.64 kN ≈ 40 tonne-force 40 tonne-force × 0.6 (to change force from tensile to shear) = 24 tonne-force. When working with a riveted or tensioned bolted joint, the strength comes from friction between the materials bolted together. Bolts are correctly torqued ...

  8. Vector (mathematics and physics) - Wikipedia

    en.wikipedia.org/wiki/Vector_(mathematics_and...

    [13] [14] [12] A simpler example of a bound vector is the translation vector from an initial point to an end point; in this case, the bound vector is an ordered pair of points in the same position space, with all coordinates having the same quantity dimension and unit (length an meters).

  9. Eddy current brake - Wikipedia

    en.wikipedia.org/wiki/Eddy_current_brake

    A linear eddy current brake in a German ICE 3 high-speed train in action. An eddy current brake, also known as an induction brake, Faraday brake, electric brake or electric retarder, is a device used to slow or stop a moving object by generating eddy currents and thus dissipating its kinetic energy as heat.
