  2. Mean speed theorem - Wikipedia

    en.wikipedia.org/wiki/Mean_speed_theorem

    The mean speed theorem, also known as the Merton rule of uniform acceleration, [1] was discovered in the 14th century by the Oxford Calculators of Merton College, and was proved by Nicole Oresme. It states that a uniformly accelerated body (starting from rest, i.e. zero initial velocity) travels the same distance as a body with uniform speed ...

  3. Three-body problem - Wikipedia

    en.wikipedia.org/wiki/Three-body_problem

    In physics, specifically classical mechanics, the three-body problem is to take the initial positions and velocities (or momenta) of three point masses that orbit each other in space and calculate their subsequent trajectories using Newton's laws of motion and Newton's law of universal gravitation.

  4. Reciprocity (electromagnetism) - Wikipedia

    en.wikipedia.org/wiki/Reciprocity_(electromagnetism)

    Now, the equation on the left-hand side of the Lorentz reciprocity theorem can be rewritten by moving the σ from the external current term () to the response field terms , and also adding and subtracting a () term, to obtain the external field multiplied by the total current = :

  5. Continuous uniform distribution - Wikipedia

    en.wikipedia.org/wiki/Continuous_uniform...

    On the other hand, the uniformly distributed numbers are often used as the basis for non-uniform random variate generation. If u {\displaystyle u} is a value sampled from the standard uniform distribution, then the value a + ( b − a ) u {\displaystyle a+(b-a)u} follows the uniform distribution parameterized by a {\displaystyle a} and b ...

    physics The natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. piezoelectricity pion Planck constant Also called Planck's constant.

  8. Lighthouse paradox - Wikipedia

    en.wikipedia.org/wiki/Lighthouse_paradox

    This thought experiment proposes that light moving in this situation is actually traveling faster than the speed of light. This presents a paradox because, according to the theory of relativity, the speed of light in vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source, and nothing can ...

  9. Electrodynamic suspension - Wikipedia

    en.wikipedia.org/wiki/Electrodynamic_suspension

    Since a train may stop at any location, due to equipment problems for instance, the entire track must be able to support both low-speed and high-speed operation. Another downside is that the repulsive system naturally creates a field in the track in front and to the rear of the lift magnets, which act against the magnets and create a form of drag.
