  2. 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 ...

  3. Zero-velocity surface - Wikipedia

    en.wikipedia.org/wiki/Zero-velocity_surface

    Jacobi constant, a Zero Velocity Surface and Curve (also Hill's curve) [1] A zero-velocity surface is a concept that relates to the N-body problem of gravity. It represents a surface a body of given energy cannot cross, since it would have zero velocity on the surface. It was first introduced by George William Hill. [2]

  4. Hill equation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Hill_equation_(biochemistry)

    Binding curves showing the characteristically sigmoidal curves generated by using the Hill equation to model cooperative binding. Each curve corresponds to a different Hill coefficient, labeled to the curve's right. The vertical axis displays the proportion of the total number of receptors that have been bound by a ligand.

  5. Brachistochrone curve - Wikipedia

    en.wikipedia.org/wiki/Brachistochrone_curve

    The curve of fastest descent is not a straight or polygonal line (blue) but a cycloid (red).. In physics and mathematics, a brachistochrone curve (from Ancient Greek βράχιστος χρόνος (brákhistos khrónos) 'shortest time'), [1] or curve of fastest descent, is the one lying on the plane between a point A and a lower point B, where B is not directly below A, on which a bead slides ...

  6. Biomechanics of sprint running - Wikipedia

    en.wikipedia.org/wiki/Biomechanics_of_sprint_running

    The second half of the test involved subjects performing a 100-m sprint on a man-made track using radar to measure the forward speed of runners to create velocity-time curves. The main result of this study showed that the force application technique (rather than simply the total amount of force applied) is the key determinant factor in ...

  7. Muscle contraction - Wikipedia

    en.wikipedia.org/wiki/Muscle_contraction

    The optimal shortening velocity for power generation is approximately one-third of maximum shortening velocity. Forcevelocity relationship relates the speed at which a muscle changes its length (usually regulated by external forces, such as load or other muscles) to the amount of force that it generates. Force declines in a hyperbolic ...

  8. Hill sphere - Wikipedia

    en.wikipedia.org/wiki/Hill_sphere

    The Hill radius or sphere (the latter defined by the former radius [citation needed]) has been described as "the region around a planetary body where its own gravity (compared to that of the Sun or other nearby bodies) is the dominant force in attracting satellites," both natural and artificial.

  9. Downhill creep - Wikipedia

    en.wikipedia.org/wiki/Downhill_creep

    Trees showing the presence of creep. Downhill creep, also known as soil creep or commonly just creep, is a type of creep characterized by the slow, downward progression of rock and soil down a low grade slope; it can also refer to slow deformation of such materials as a result of prolonged pressure and stress.
