  2. Inelastic collision - Wikipedia

    en.wikipedia.org/wiki/Inelastic_collision

    A completely inelastic collision between equal masses. A perfectly inelastic collision occurs when the maximum amount of kinetic energy of a system is lost. In a perfectly inelastic collision, i.e., a zero coefficient of restitution, the colliding particles stick together. In such a collision, kinetic energy is lost by bonding the two bodies ...

  3. Elastic collision - Wikipedia

    en.wikipedia.org/wiki/Elastic_collision

    Five atoms are colored red so their paths of motion are easier to see. In physics, an elastic collision is an encounter (collision) between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise ...

  4. Coefficient of restitution - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_restitution

    e = 0: This is a perfectly inelastic collision. 0 < e < 1: This is a real-world inelastic collision, in which some kinetic energy is dissipated. e = 1: This is a perfectly elastic collision, in which no kinetic energy is dissipated, and the objects rebound from one another with the same relative speed with which they approached.

  5. Compton scattering - Wikipedia

    en.wikipedia.org/wiki/Compton_scattering

    From this perspective, Compton scattering could be considered elastic because the internal state of the electron does not change during the scattering process. In the latter perspective, the atom's state is change, constituting an inelastic collision. Whether Compton scattering is considered elastic or inelastic depends on which perspective is ...

  6. Collision - Wikipedia

    en.wikipedia.org/wiki/Collision

    If kinetic energy is lost, it is an inelastic collision. The diagram does not show whether the illustrated collision was elastic or inelastic, because no velocities are provided. The most one can say is that the collision was not perfectly inelastic, because in that case the ball would have stuck to the wall.

  7. Inelastic scattering - Wikipedia

    en.wikipedia.org/wiki/Inelastic_scattering

    Inelastic scattering. In chemistry, nuclear physics, and particle physics, inelastic scattering is a process in which the internal states of a particle or a system of particles change after a collision. Often, this means the kinetic energy of the incident particle is not conserved (in contrast to elastic scattering).

  8. Constitutive equation - Wikipedia

    en.wikipedia.org/wiki/Constitutive_equation

    which depends on the materials A and B are made from, since the collision involves interactions at the surfaces of A and B. Usually 0 ≤ e ≤ 1, in which e = 1 for completely elastic collisions, and e = 0 for completely inelastic collisions. It is possible for e ≥ 1 to occur – for superelastic (or explosive) collisions.

  9. Elasticity (physics) - Wikipedia

    en.wikipedia.org/wiki/Elasticity_(physics)

    e. In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after ...
