  2. Variable speed of light - Wikipedia

    en.wikipedia.org/wiki/Variable_speed_of_light

    Spatial variation of the speed of light in a gravitational potential as measured against a distant observer's time reference is implicitly present in general relativity. [3] The apparent speed of light will change in a gravity field and, in particular, go to zero at an event horizon as viewed by a distant observer. [4]

  3. Orders of magnitude (speed) - Wikipedia

    Approaching velocity of Messier 98 to our galaxy. 192,000: 690,000: 430,000 0.00064: Predicted [needs update] top speed of the Parker Solar Probe at its closest perihelion in 2024. [29] [30] 200,000: 700,000: 450,000 0.00070: Orbital speed of the Solar System in the Milky Way galaxy. 308,571: 1,080,000: 694,288 0.001: Approaching velocity of ...

  4. Rapidity - Wikipedia

    en.wikipedia.org/wiki/Rapidity

    Rapidity is the value of artanh(v / c) for velocity v and speed of light c. In special relativity, the classical concept of velocity is converted to rapidity to accommodate the limit determined by the speed of light. Velocities must be combined by Einstein's velocity-addition formula. For low speeds, rapidity and velocity are almost exactly ...

  5. Motion graphs and derivatives - Wikipedia

    en.wikipedia.org/wiki/Motion_graphs_and_derivatives

    Since the velocity of the object is the derivative of the position graph, the area under the line in the velocity vs. time graph is the displacement of the object. (Velocity is on the y-axis and time on the x-axis. Multiplying the velocity by the time, the time cancels out, and only displacement remains.)

  7. Classical mechanics - Wikipedia

    en.wikipedia.org/wiki/Classical_mechanics

    Mathematically, if the velocity of the first object in the previous discussion is denoted by the vector u = ud and the velocity of the second object by the vector v = ve, where u is the speed of the first object, v is the speed of the second object, and d and e are unit vectors in the directions of motion of each object respectively, then the ...

  8. Strain-rate tensor - Wikipedia

    en.wikipedia.org/wiki/Strain-rate_tensor

    A two-dimensional flow that, at the highlighted point, has only a strain rate component, with no mean velocity or rotational component. In continuum mechanics, the strain-rate tensor or rate-of-strain tensor is a physical quantity that describes the rate of change of the strain (i.e., the relative deformation) of a material in the neighborhood of a certain point, at a certain moment of time.

  9. Proper velocity - Wikipedia

    en.wikipedia.org/wiki/Proper_velocity

    Log-log plot of γ (blue), v/c (cyan), and η (yellow) versus proper velocity w/c (i.e. momentum p/mc).Note that w/c is tracked by v/c at low speeds and by γ at high speeds. The dashed red curve is γ − 1 (kinetic energy K/mc 2), while the dashed magenta curve is the relativistic Doppler factor.
