Question

Why doesn't action and reaction balance each other

Answer 1

Although action and reaction forces are always equal and opposite to each other, they are acting on two different objects. Saying that the forces balance each otherimplies that they are adding up to equal zero. Forces are only added when they are acting on the same object, not on different objects

Answer 2

Explanation:

Newton's third law of motion states that every action has an equal and opposite reaction. This means that forces always act in pairs. Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don't cancel out.
