The laws | Math record of law | Formulation of the law |
1) Newton’s law |
| Anybody, as long as it remains isolated, retains its state of rest or uniform rectilinear motion (the acceleration of the body a is zero). |
2) Newton’s law |
| The product of the mass of a body by the acceleration it received from the action of the force A of another body, equal to the force A |
3) Newton’s law |
| There is always an equal and opposite reaction to action |
Stefan-Boltzmann law of thermal radiation of solids |
| The density of the flux of thermal radiation q12 incident from body 1 to body 2 is directly proportional to the temperature difference of the bodies to the fourth degree. |
Ohm’s law |
| The current flowing in the conductor is directly proportional to the voltage applied to it and inversely proportional to the resistance of the conductor. |
Planck’s Law |
| The density of the heat radiation flux in the blackbody is inversely proportional to the wavelength and directly proportional to the body temperature. |
Wine Law |
| The wavelength at which the blackbody radiation density reaches its maximum value is inversely proportional to body temperature. |
Einstein’s law for photoelectric effect |
| The energy of a photon descending to the cathode, followed by the emission of an electron by the cathode, is equal to the exit energy and the kinetic energy of the electron. |
Bohr’s Postulates | - | 1) In a stationary state, the atom does not emit. 2) When an atom transfers from a state with a higher energy to a state with a lower energy, when an electron in an atom jumps from an orbit more remote from the nucleus, a quantum of electromagnetic, thermal radiation is emitted 3) In a stationary state, an electron moves in a certain orbit, a Coulomb force acts on an electron in an atom. |
