Which term refers to a situation where two or more objects crash into each other?

The term that accurately describes a situation where two or more objects crash into each other is "collision." This term specifically denotes the act of two or more physical entities coming into contact with significant force, which typically results in damage or disruption to the objects involved.

While "impact" and "crash" can also convey a similar idea, "impact" refers more broadly to the force or effect of one object striking another and may not always imply a sustained contact or damage. "Crash" is often used in a colloquial context or to describe more severe incidents, but it doesn't encompass all scenarios of objects colliding.

"Incident," on the other hand, is a more general term that can refer to any event, not necessarily involving a physical collision. Thus, "collision" is the most precise term for describing the scenario where two or more objects come into forceful contact with each other.
