Question

what is the difference between action and reaction?
(line difference...)

Answer 1

Explanation:

is that action is something done so as to accomplish a purpose

while reaction is an action or statement in response to a stimulus or other event.

“Action” means any act or occurrence or event or the committing/performing of an activity.

“Reaction” as in “Re-action” literally means the action done again but only in response to the action or as a retaliatory measure or as an answer or as a rejoinder/rebuttal.

hope it's help
