  2. Brownian ratchet - Wikipedia

    en.wikipedia.org/wiki/Brownian_ratchet

    Schematic figure of a Brownian ratchet. In the philosophy of thermal and statistical physics, the Brownian ratchet or Feynman–Smoluchowski ratchet is an apparent perpetual motion machine of the second kind (converting thermal energy into mechanical work), first analysed in 1912 as a thought experiment by Polish physicist Marian Smoluchowski. [1]

  3. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    The larger scales of imperceptible motions are difficult for humans to perceive for two reasons: Newton's laws of motion (particularly the third), which prevents the feeling of motion on a mass to which the observer is connected, and the lack of an obvious frame of reference that would allow individuals to easily see that they are moving. [9 ...

  4. Equations of motion - Wikipedia

    en.wikipedia.org/wiki/Equations_of_motion

    There are two main descriptions of motion: dynamics and kinematics.Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations.

  5. Brownian motion - Wikipedia

    en.wikipedia.org/wiki/Brownian_motion

    Brownian motion is the random motion of particles suspended in a medium (a liquid or a gas). [2] This motion pattern typically consists of random fluctuations in a particle's position inside a fluid sub-domain, followed by a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume.

    en.wikipedia.org/wiki/Mercedes-Benz_9G-Tronic...

    9G-Tronic is Mercedes-Benz's trademark name for its 9-speed automatic transmission, starting off with the W9A 700 (Wandler-9-Gang-Automatik bis 700 N⋅m Eingangsdrehmoment; converter-9-gear-automatic with 700 N⋅m (516 lb⋅ft) maximum input torque; type 725.0 [1]) as core model.

  7. Kinematics - Wikipedia

    en.wikipedia.org/wiki/Kinematics

    Kinematics is a subfield of physics and mathematics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move.

  8. Convair Model 58-9 - Wikipedia

    en.wikipedia.org/wiki/Convair_Model_58-9

    The Model 58-9 was expected to have a maximum take-off weight of 190,000 pounds (86,000 kg), and would have a range of 2,500 nautical miles (4,600 km; 2,900 mi) at a cruising speed of Mach 2.4. If the project had been approved, it was projected by Convair that the first prototype of the airliner could fly within three years of the project being ...

  9. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    Since linear motion is a motion in a single dimension, the distance traveled by an object in particular direction is the same as displacement. [4] The SI unit of displacement is the metre . [ 5 ] [ 6 ] If x 1 {\displaystyle x_{1}} is the initial position of an object and x 2 {\displaystyle x_{2}} is the final position, then mathematically the ...
