Physical Laws

This is a list of physical laws discovered by science.

$c_V = \frac{3R} {M}$

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)

$F_g = \frac{Gm_1m_2} {r_2}$

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

$V = \frac {I} {R}$

Kirchhoff's Laws (current and voltage laws)
Maxwell's equations (electric and magnetic fields: in vacuum ·E = 0, ·B = 0, ×E = -∂B/∂t, ×B = c^-2∂E/∂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 = k_w
- Stefan-Boltzmann law (total radiation from a blackbody)

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