3rd law

Explanation:

Newton's 1st Law (Law of Inertia) states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This shows that all masses resist changing their motion (inertia). Newton's 2nd Law is about the relationship between force \(F = ma\) (mass \(m\) and acceleration \(a\)). Newton's 3rd Law is about action - reaction pairs (\(F_{action}=-F_{reaction}\)).

Answer:

1st Law
