Common mistake
Misunderstanding Newton's Third Law
Students often think that Newton's third law means that forces cancel each other out, leading to confusion about how objects interact.
Clarify that Newton's third law states that for every action, there is an equal and opposite reaction, and these forces act on different objects, not on the same object.
