Newton's laws of motion
Third law
Whenever a particle A exerts a force on another particle B, B simultaneously exerts a force on A with the same magnitude in the opposite direction. The strong form of the law further postulates that these two forces act along the same line. This law is often simplified into the sentence
"Every action has an equal and opposite reaction."
Think before you do anything. Expect the opposite result always, and prepared for it!
