The shapes of the first five atomic orbitals are 1s, 2s, 2px, 2pz, and 2py. The two colors show the phase or sign of the wave function in each region. Each picture is domain coloring of a ψ(x, y, z) function which depends on the coordinates of one electron. To see the elongated shape of ψ(x, y, z)2 functions that show probability density more directly, see pictures of d-orbitals below.

Velocity of the particle m with respect to the origin O can be resolved into components parallel to (v∥) and perpendicular to (v⊥) the radius vector r. The angular momentum of m is proportional to the perpendicular component v⊥ of the velocity, or equivalently, to the perpendicular distance r⊥ from the origin.

$Émilie du Châtelet (1706–1749) was the first to publish the relation for kinetic energy E kin ∝ m v 2 {\displaystyle E_{\text{kin}}\propto mv^{2}} , derived from the experimental observation of objects dropped into clay. (Portrait by Maurice Quentin de La Tour.)$
