  2. Kinetic energy - Wikipedia

    en.wikipedia.org/wiki/Kinetic_energy

    The total kinetic energy of a system depends on the inertial frame of reference: it is the sum of the total kinetic energy in a center of momentum frame and the kinetic energy the total mass would have if it were concentrated in the center of mass.

  3. Tests of relativistic energy and momentum - Wikipedia

    en.wikipedia.org/wiki/Tests_of_relativistic...

    Kinetic energy in special relativity and Newtonian mechanics. Relativistic kinetic energy increases to infinity when approaching the speed of light, thus no massive body can reach this speed. Tests of relativistic energy and momentum are aimed at measuring the relativistic expressions for energy, momentum, and mass.

  4. Specific kinetic energy - Wikipedia

    en.wikipedia.org/wiki/Specific_kinetic_energy

    The specific kinetic energy of a system is a crucial parameter in understanding its dynamic behavior and plays a key role in various scientific and engineering applications. Specific kinetic energy is an intensive property, whereas kinetic energy and mass are extensive properties. The SI unit for specific kinetic energy is the joule per ...

  5. Virial theorem - Wikipedia

    en.wikipedia.org/wiki/Virial_theorem

    The significance of the virial theorem is that it allows the average total kinetic energy to be calculated even for very complicated systems that defy an exact solution, such as those considered in statistical mechanics; this average total kinetic energy is related to the temperature of the system by the equipartition theorem.

  6. Rotational energy - Wikipedia

    en.wikipedia.org/wiki/Rotational_energy

    An example is the calculation of the rotational kinetic energy of the Earth. As the Earth has a sidereal rotation period of 23.93 hours, it has an angular velocity of 7.29 × 10 −5 rad·s −1. [2] The Earth has a moment of inertia, I = 8.04 × 10 37 kg·m 2. [3] Therefore, it has a rotational kinetic energy of 2.14 × 10 29 J.

  7. König's theorem (kinetics) - Wikipedia

    en.wikipedia.org/wiki/König's_theorem_(kinetics)

    The second part expresses the kinetic energy of a system of particles in terms of the velocities of the individual particles and the centre of mass.. Specifically, it states that the kinetic energy of a system of particles is the sum of the kinetic energy associated to the movement of the center of mass and the kinetic energy associated to the movement of the particles relative to the center ...

    Here is a very early, initial look at the Democratic Party politicians considered to be potential 2028 presidential contenders in the next race for the White House.

  9. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    The concept of energy became a key part of Newtonian mechanics in the post-Newton period. Huygens' solution of the collision of hard spheres showed that in that case, not only is momentum conserved, but kinetic energy is as well (or, rather, a quantity that in retrospect we can identify as one-half the total kinetic energy).
