The kinetic energy is equal to 1/2 the product of the mass and the square of the speed. In formula form: where is the mass and is the speed (magnitude of the velocity) of the body. In SI units, mass is measured in kilograms, speed in metres per second, and the resulting kinetic energy is in joules.
Physics Physique Физика, also known as various punctuations of Physics, Physique, Fizika, and as Physics for short, was a scientific journal published from 1964 through 1968. [1] [2] Founded by Philip Warren Anderson and Bernd T. Matthias, who were inspired by wide-circulation literary magazines like Harper's, the journal's original goal ...
The Davisson–Germer experiment was a 1923–1927 experiment by Clinton Davisson and Lester Germer at Western Electric (later Bell Labs), [1][2][3] in which electrons, scattered by the surface of a crystal of nickel metal, displayed a diffraction pattern. This confirmed the hypothesis, advanced by Louis de Broglie in 1924, of wave-particle ...
Delta-v (also known as " change in velocity "), symbolized as and pronounced deltah-vee, as used in spacecraft flight dynamics, is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon, or an in-space orbital maneuver. It is a scalar that has the units of ...
The Physics of Metals and Metallography ( Phys. Met. Metallogr.) [ Russian: Физика металлов и металловедение ( ФММ ), or Fizika metallov i metallovedenie ( Fiz. Met. Metalloved. )] is a peer-reviewed Russian scientific journal concerning metals and metal alloys. It was established in 1955 by the Academy of ...
Galilean transformation. In physics, a Galilean transformation is used to transform between the coordinates of two reference frames which differ only by constant relative motion within the constructs of Newtonian physics. These transformations together with spatial rotations and translations in space and time form the inhomogeneous Galilean ...
Victor Vasil'evich Borisov (Russian: Виктор Васильевич Борисов) (31 October 1937 – 5 December 2013) was a Russian physicist and mathematician who contributed to the theory of wave motion, in particular to time domain electromagnetics and localized waves.
In science, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled. A force is said to do positive work if it has a component in the ...
