  1. Hace 2 días · Combined with other laws of physics, the two postulates of special relativity predict the equivalence of mass and energy, as expressed in the mass–energy equivalence formula =, where is the speed of light in a vacuum.

  2. Hace 1 día · When you first learn about mass, it's often introduced as the coefficient that relates the force applied to an object to how the object accelerates. In short, we have the definition of the inertial mass as \[m=\frac{\big|\vec{F}\big|}{|\vec{a}|}\] from Newton's second law.

  4. Hace 3 días · We consider a Dirac operator with constant magnetic field defined on a half-plane with boundary conditions that interpolate between infinite mass and zigzag. By a detailed study of the energy dispersion curves, we show that the infinite mass case generically captures the profile of these curves, which undergoes a continuous pointwise deformation into the topologically different zigzag profile ...

    Hace 1 día · The 2.7 million Kelvin photon temperature gives a typical photon energy of 250 electronvolt, thereby setting a typical mass scale for warm dark matter: particles much more massive than this, such as GeV–TeV mass WIMPs, would become non-relativistic much earlier than one year after the Big Bang and thus have FSLs much smaller than a protogalaxy, making them cold.

  6. Hace 1 día · In mathematical analysis, the Dirac delta function (or δ distribution ), also known as the unit impulse, [1] is a generalized function on the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one.

  7. Hace 5 días · If a perfectly elastic ball collides with a fixed surface, it rebounds with the same speed. A fixed surface can be treated as an infinite mass object with zero speed.
