List of laws in science

This is a list of physical laws discovered by science.

  • Boyle's Law (pressure and volume of ideal gas)

  • Charles & Gay-Lussac (gases expand equally with the same change of temperature)

  • Dulong-Petit law (specific heat capacity at constant volume)

 c_V = \frac{3R} {M}

  • Einstein
    • Relativity E = mc2 (Energy = mass speed of light2)

  • Laws of Kepler (planetary motion)

  • Beer-Lambert (light absorption)

  • Newton

    • Newton's laws of motion (inertia, F = ma, action and reaction)

    • Law of heat conduction

    • General law of gravitation (universal gravitation force)

 F_g = \frac{Gm_1m_2} {r_2}

  • Coulomb's law

 F = \frac{\left|q_1 q_2\right|}{4 \pi \epsilon_0 r^2}

  • Ohm's Law

 V = \frac {I} {R}

  • Kirchhoff's Laws (current and voltage laws)

  • Maxwell's equations (electric and magnetic fields: in vacuum Image:del.gifE = 0, Image:del.gifB = 0, Image:del.gifE = -∂B/∂t, Image:del.gifB = c-2E/∂t)

  • Poiseuille's law (voluminal laminar stationary flow of incompressible uniform viscous liquid through a cylindrical tube with the constant circular cross-section)

 \Phi_{V} = {\pi r^{4}\over 8 \eta} { \triangle p^{\star} \over l}

  • Radiation laws

    • Planck's Law of Radiation (spectral density in a radiation of a blackbody)

    • Wien's law (wavelength of the peak of the emission of a blackbody) λ0T = kw

    • Stefan-Boltzmann law (total radiation from a blackbody)

 j^{\star} = \sigma T^4
