a collision in which the total kinetic energy of the colliding bodies or particles is the same after the collision as it was before (opposed to ).
A collision between bodies in which the total kinetic energy of the bodies is conserved. In a perfectly elastic collision, no energy is dissipated as heat energy internal to the bodies, and none is spent on permanently deforming the bodies or radiated away in some other fashion. Elastic collisions, such as the collision of a rubber ball on a hard surface, result in the reflection or “bouncing” of bodies away from each other. Comapre inelastic collision.
noun, Physics. 1. the temporary change in length, volume, or shape produced in an elastic substance by a stress that is less than the elastic limit of the substance.
- Elastic fiber
elastic fiber n. Any of the fibers 0.2 to 2 micrometers in diameter containing elastin. They branch and anastomose to form networks and fuse to form fenestrated membranes. Also called yellow fiber.
