Consider a perfectly inelastic collision between two protons: an incident proton with mass $m_{p},$ kinetic energy K, and momentum magnitude p joins with an originally stationary target proton to form a single product particle of mass M. Not all the kinetic energy of the incoming proton is available to create the product particle because conservation of momentum requires that the system as a whole still must have some kinetic energy after the collision.

The main difference between the two processes is regeneration results in the damaged cells replaced by identical cells through mitosis while fibrosis replaces the damaged cells with a network of collagen and . Fibrosis, also known as fibrotic scarring, is a pathological wound healing in which connective tissue replaces normal parenchymal tissue to the extent that it goes unchecked, leading to considerable tissue remodelling and the formation of permanent scar tissue.Repeated injuries, chronic inflammation and repair are susceptible to fibrosis where an accidental excessive accumulation of extracellular matrix components, such as the collagen is produced by fibroblasts, leading to the formation of a permanent fibrotic scar.In response to injury, this is called scarring, and if fibrosis arises from a single cell line, this is called a fibroma.
