Also, for dissipative forces another function must be introduced alongside L.

However, when such a system is coupled to a dissipative force, then the tunneling becomes possible.

Experiments include the use of air tracks to study acceleration, collisions, dissipative forces, and periodic motion.

Construct velocity-dependent dissipative force on atom with two red detuned laser beams:

Thus, the Newtonian equation for the particle () must contain a dissipative force (damping term), which takes into account this energy loss.

It may eventually be reduced to a remnant containing about a dozen star systems, most of them binary or multiple, which will remain vulnerable to ongoing dissipative forces.

It does not always work for non-conservative forces or dissipative forces like friction, in which case one may revert to Newtonian mechanics, or use the Udwadia-Kalaba equation.

A perpetual motion machine of the third kind, usually (but not always) defined as one that completely eliminates friction and other dissipative forces, to maintain motion forever (due to its mass inertia).
