  2. Kinetic energy - Wikipedia

    en.wikipedia.org/wiki/Kinetic_energy

    [1] In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling at a speed v is . [2] The kinetic energy of an object is equal to the work, or force in the direction of motion times its displacement , needed to accelerate the mass from rest to its stated velocity.

    Its initial value is 1 (when v = 0); and as velocity approaches the speed of light (vc) γ increases without bound (γ → ∞). α (Lorentz factor inverse) as a function of velocity—a circular arc. In the table below, the left-hand column shows speeds as different fractions of the speed of light (i.e. in units of c). The middle column ...

    If its temperature is allowed to change by 1 °C, its mass changes by 1.5 picograms (1 pg = 1 × 10 −12 g). [note 5] A spinning ball has greater mass than when it is not spinning. Its increase of mass is exactly the equivalent of the mass of energy of rotation, which is itself the sum of the kinetic energies of all the moving parts of the ball.

    en.wikipedia.org/wiki/V12_engine

    Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and secondary engine balance.A four-stroke V12 engine has even firing order at V-angles of 60, 120, or 180 degrees [1] [unreliable source] Many V12 engines use a V-angle of 60 degrees between the two banks of cylinders. [2]

    Top: frame F′ moves at velocity v along the x-axis of frame F. Bottom: frame F moves at velocity −v along the x′-axis of frame F′. [5] The invariant interval can be seen as a non-positive definite distance function on spacetime. The set of transformations sought must leave this distance invariant.

  7. Talk:Kinetic energy - Wikipedia

    en.wikipedia.org/wiki/Talk:Kinetic_energy

    Jain is writing for engineers who need to apply KE to practical problems. Assigning object KE is a routine part of newtonian mechanics. The total KE of a system is partitioned among the objects as part of leveraging conservation of energy. That does not mean KE is an intrinsic property of the objects, but rather a form of bookkeeping.

    The National Highway Traffic Safety Administration is investigating reports of alleged engine failures in GM's 6.2-liter L87 V-8, an engine used in a wide variety of trucks and SUVs.

    Note that the mobility μ = v d /F can be calculated based on the viscosity of the gas; Therefore, the Einstein–Smoluchowski equation also provides a relation between the mass diffusivity and the viscosity of the gas.
