12.6 Reaction Mechanisms – Chemistry

For example, the gas-phase decomposition of cyclobutane, C 4 H 8, to ethylene, C 2 H 4, occurs via a unimolecular, single-step mechanism: For these unimolecular reactions to occur, all that is required is the separation of parts of single reactant molecules into products.

Shock absorber - Wikipedia

A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).
