A major element of a collision-induced gravity model that has not been yet explained is how the heat generated in the inelastic collision
is carried-off from the local neighborhood of the 3D coordinates of the collision.
 first proposed the wounded nucleon model which was based on the basic assumption that the inelastic collisions
of two nuclei can be described as an incoherent composition of the collisions of individual nucleons of the colliding nuclei.
Certainly considering all collisions as being elastic avoids having to contemplate the various frequencies of radiation that would be associated with inelastic collisions
. And when in equilibrium; since the mean kinetic energy of the gas molecules is constant then yes the mean magnitude of momentum remains constant but this is no longer a requirement for an elastic gas-wall collision!
Some applications ofthe developed method to the derivation of kinetic equations in scaling limits of large particle systems of different kinds, in particular, hard spheres with inelastic collisions
, are considered in papers [38, 41, 42].
The topics include physics and measurement, inertia and Newton's second and third laws, blocks in trains and in contact, non-uniform circular motion, the work-energy theorem, systems of particles and center of mass, completely inelastic collisions
, moments of inertia theorems, angular momentum, and gravitational effects and dynamics.
In inelastic collisions
, like most completed tackle events, the sum kinetic energy of the ball-carrier and tackler before the tackle is equal to the total kinetic energy after the tackle (when the ball-carrier and tackler are in full contact, and have become one system).
Collisions can be taken as completely inelastic collisions
He then proceeds to describing applications of non-relativistic quantum-mechanical theory to energetic inelastic collisions
of ions with atoms, including the physics of double scatterings, Coulomb-Born type methods for electron detachment, and Thomas double scatterings.

The light arising from these inelastic collisions
is called Raman scattering, after Sir C.
