  2. Force - Wikipedia

    en.wikipedia.org/wiki/Force

    The static friction increases or decreases in response to the applied force up to an upper limit determined by the characteristics of the contact between the surface and the object. [3] A static equilibrium between two forces is the most usual way of measuring forces, using simple devices such as weighing scales and spring balances.

  3. Static forces and virtual-particle exchange - Wikipedia

    en.wikipedia.org/wiki/Static_forces_and_virtual...

    Static force fields are fields, such as a simple electric, magnetic or gravitational fields, that exist without excitations.The most common approximation method that physicists use for scattering calculations can be interpreted as static forces arising from the interactions between two bodies mediated by virtual particles, particles that exist for only a short time determined by the ...

  4. Stevens's power law - Wikipedia

    en.wikipedia.org/wiki/Stevens's_power_law

    Stevens' power law is an empirical relationship in psychophysics between an increased intensity or strength in a physical stimulus and the perceived magnitude increase in the sensation created by the stimulus.

  5. Statics - Wikipedia

    en.wikipedia.org/wiki/Statics

    Force is the action of one body on another. A force is either a push or a pull, and it tends to move a body in the direction of its action. The action of a force is characterized by its magnitude, by the direction of its action, and by its point of application (or point of contact). Thus, force is a vector quantity, because its effect depends ...

  6. Dynamic pressure - Wikipedia

    en.wikipedia.org/wiki/Dynamic_pressure

    The dynamic pressure, along with the static pressure and the pressure due to elevation, is used in Bernoulli's principle as an energy balance on a closed system. The three terms are used to define the state of a closed system of an incompressible, constant-density fluid.

  7. Static electricity - Wikipedia

    en.wikipedia.org/wiki/Static_electricity

    Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor. [1]

  8. Static cling - Wikipedia

    en.wikipedia.org/wiki/Static_cling

    Static cling is the tendency for light objects to stick (cling) to other objects owing to static electricity. It is common in clothing, but occurs with other items, such as the tendency of dust to be attracted to, and stick to, plastic items.

  9. Triboelectric effect - Wikipedia

    en.wikipedia.org/wiki/Triboelectric_effect

    Nanotribology, science of tribology (friction, lubrication and wear processes) at the nanoscale; Piezoelectricity, polarization due to linear strains; Polarization density, general description of the physics of polarization; Static electricity, electric charge often but not always due to triboelectricity
