How is the word impact different from other nouns like it?

Some common synonyms of impact are collision, concussion, and shock. While all these words mean "a forceful, even violent contact between two or more things," impact may be used to imply contact between two things, at least one of which is impelled toward the other.

In some situations, the words concussion and impact are roughly equivalent. However, concussion when not in technical use, often suggests the shattering, disrupting, or weakening effects of a collision, explosion, or blow.

When could shock be used to replace impact?

The synonyms shock and impact are sometimes interchangeable, but shock often denotes the effect produced by a collision and carries the suggestion of something that strikes or hits with force.
