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.

Liquid helium retains kinetic energy and does not freeze regardless of temperature at standard atmospheric pressure due to zero-point energy. When cooled below its Lambda point, it exhibits properties of superfluidity.

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.

Helium II will "creep" along surfaces in order to find its own level—after a short while, the levels in the two containers will equalize. The Rollin film also covers the interior of the larger container; if it were not sealed, the helium II would creep out and escape.
