epäelastisia
Epäelastisia is a Finnish adjective that translates to "inelastic" in English. It is primarily used in physics and materials science to describe a material or collision where kinetic energy is not conserved. In the context of materials, an inelastic material undergoes permanent deformation when subjected to stress beyond its elastic limit. This means that once the stress is removed, the material does not return to its original shape. Examples of inelastic behavior in materials include plastic deformation, fracture, and yielding.
In the context of collisions, an inelastic collision is one where some or all of the kinetic
