a collision in which the total kinetic energy of the colliding bodies or particles is not 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 not conserved. In an inelastic collision, the total momentum of the two bodies remains the same, but some of the initial kinetic energy is transformed into heat energy internal to the bodies, used up in deforming the bodies, or radiated away in some other fashion. Inelastic collisions, such as the collision of two balls of clay, tend to result in the slowing and sometimes the joining together of the colliding bodies. Comapre elastic collision.
- Inelastic demand
Demand whose percentage change is less than a percentage change in price. For example, if the price of a commodity rises twenty-five percent and demand decreases by only two percent, demand is said to be inelastic. (See elasticity.)
[in-i-las-tik] /ˌɪn ɪˈlæs tɪk/ adjective 1. not ; lacking flexibility or resilience; unyielding. 2. Economics. relatively unresponsive to changes, as demand when it fails to increase in proportion to a decrease in price. Compare (def 6). /ˌɪnɪˈlæstɪk/ adjective 1. not elastic; not resilient 2. (physics) (of collisions) involving an overall decrease in translational kinetic energy […]
noun, Physics. 1. a scattering of particles due to an inelastic collision that also changes their wavelengths and phases.
- Inelastic supply
Supply whose percentage change is less than a percentage change in price. For example, if the price of a commodity drops twenty-five percent and supply decreases by only two percent, supply is said to be inelastic. (See elasticity.)
