• noun Synonyms Shock, Collision, Concussion, Jolt. A shock is a violent shaking, and may be produced by a collision, a heavy jolt, or otherwise; it may be of the nature of a concussion. The word is more often used of the effect than of the action: as, the shock of battle, a shock of electricity, the shock from the sudden announcement of bad news. A collision is the dashing of a moving body upon a body moving or still: as, a railroad collision; collision of steamships. Concussion is a shaking together; hence the word is especially applicable where that which is shaken has, or may be thought of as having, parts: as, concussion of the air or of the brain. Collision implies the solidity of the colliding objects: as, the collision of two cannon-balls in the air. A jolt is a shaking by a single abrupt jerking motion upward or downward or both, as by a springless wagon on a rough road. Shock is used figuratively; we speak sometimes of the collision of ideas or of minds: concussion and jolt are only literal.
