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

When is it sensible to use collision instead of concussion?

The words collision and concussion can be used in similar contexts, but collision implies the coming together of two or more things with such force that both or all are damaged or their progress is severely impeded.

When can impact be used instead of concussion?

The synonyms impact and concussion are sometimes interchangeable, but impact may be used to imply contact between two things, at least one of which is impelled toward the other.

When is shock a more appropriate choice than concussion?

The words shock and concussion are synonyms, but do differ in nuance. Specifically, shock often denotes the effect produced by a collision and carries the suggestion of something that strikes or hits with force.
