  2. Tension (physics) - Wikipedia

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

    Tension is the pulling or stretching force transmitted axially along an object such as a string, rope, chain, rod, truss member, or other object, so as to stretch or pull apart the object. In terms of force, it is the opposite of compression. Tension might also be described as the action-reaction pair of forces acting at each end of an object.

  3. Spinning drop method - Wikipedia

    en.wikipedia.org/wiki/Spinning_Drop_Method

    The relation between the surface tension and angular velocity of a droplet can be obtained in different ways. One of them involves considering the total mechanical energy of the droplet as the summation of its kinetic energy and its surface energy: = +

  4. Hill's muscle model - Wikipedia

    en.wikipedia.org/wiki/Hill's_muscle_model

    is the maximum velocity, when = Although Hill's equation looks very much like the van der Waals equation, the former has units of energy dissipation, while the latter has units of energy. Hill's equation demonstrates that the relationship between F and v is hyperbolic. Therefore, the higher the load applied to the muscle, the lower the ...

  5. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    Newton's laws are often stated in terms of point or particle masses, that is, bodies whose volume is negligible. This is a reasonable approximation for real bodies when the motion of internal parts can be neglected, and when the separation between bodies is much larger than the size of each.

  6. Hooke's law - Wikipedia

    en.wikipedia.org/wiki/Hooke's_law

    In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.

  7. Viscous stress tensor - Wikipedia

    en.wikipedia.org/wiki/Viscous_stress_tensor

    In particular, the local strain rate E(p, t) is the only property of the velocity flow that directly affects the viscous stress ε(p, t) at a given point. On the other hand, the relation between E and ε can be quite complicated, and depends strongly on the composition, physical state, and microscopic structure of the material. It is also often ...

  8. Dispersion (water waves) - Wikipedia

    en.wikipedia.org/wiki/Dispersion_(water_waves)

    This is because shallow water waves are not dispersive. In deep water, the group velocity is equal to half the phase velocity: {{math|c g = ⁠ 1 / 2 ⁠ c p. [7] The group velocity also turns out to be the energy transport velocity. This is the velocity with which the mean wave energy is transported horizontally in a narrow-band wave field. [8 ...

  9. Capillary wave - Wikipedia

    en.wikipedia.org/wiki/Capillary_wave

    Capillary waves (ripples) in water Ripples on Lifjord in Øksnes Municipality, Norway Capillary waves produced by droplet impacts on the interface between water and air.. A capillary wave is a wave traveling along the phase boundary of a fluid, whose dynamics and phase velocity are dominated by the effects of surface tension.
