What is another word for law of action and reaction?
Pronunciation: [lˈɔː ɒv ˈakʃən and ɹɪˈakʃən] (IPA) 
Law of action and reaction, also known as Newton's Third Law of motion states that for every action, there is an equal and opposite reaction. This law is a fundamental principle in physics and is applicable in various fields. Synonyms for the law of action and reaction include Newton's third law, the principle of inertia, and the law of cause and effect. The principle of inertia explains that an object at rest will remain at rest, and an object in motion will continue to move at the same speed and in the same direction unless acted upon by an external force. The law of cause and effect asserts that every action has a consequence, and every effect has a cause.
