Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal n̂, d is the dipole moment between two point charges, the volume density of these is the polarization density P.

It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = π r 2 h and τ = rF sinθ. When a variable with an exponent or in a function is covered, the corresponding inverse is applied to the remainder, i.e. = and = .
In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion. [ 1 ] In classical mechanics , the kinetic energy of a non-rotating object of mass m traveling at a speed v is 1 2 m v 2 {\textstyle {\frac {1}{2}}mv^{2}} .
A binary prefix is a unit prefix that indicates a multiple of a unit of measurement by an integer power of two.The most commonly used binary prefixes are kibi (symbol Ki, meaning 2 10 = 1024), mebi (Mi, 2 20 = 1 048 576), and gibi (Gi, 2 30 = 1 073 741 824).
