collision

Two things smashing

A collision is an impact between moving objects—two cars, two particles, two people rounding a corner.

The word emphasizes forceful contact: The collision totaled both vehicles.

Extended uses describe conflicts between incompatible things: a collision of ideas, a collision of cultures, scheduling collisions.

In computing, a collision occurs when two pieces of data compete for the same space or identifier.
