Wikipedia Meaning and Definition on 'Dissipating'

In physics, dissipation embodies the concept of a dynamical system where important mechanical modes, such as waves or oscillations, lose energy over time, typically due to the action of friction or turbulence. The lost energy is converted into heat, raising the temperature of the system. Such systems are called dissipative systems.

For example, a wave that loses amplitude is said to dissipate. The precise nature of the effects depends on the nature of the wave: an atmospheric wave, for instance, may dissipate close to the surface due to friction with the land mass, and at higher levels due to radiative cooling.

Dissipating forces are those which can not be described by Hamiltonian formalism. Loosely speaking, friction and all similar forces which result in decoherency of energy, that is, conversion of coherent or directed energy flow into an indirected or more isotropic distribution of energy.
