The action and reaction forces are reciprocal (opposite) on an object.
Newton's Third Law of Motion
Examples of Action = Reaction Forces
A person pushes against a wall (action force), and the wall exerts an equal and opposite force against the person (reaction force). |
Action - Reaction Forces DO NOT Cancel Each Other Out
Even though the forces are equal in magnitude (strength) and opposite in direction, they do not cancel each other.
This law addresses two objects, each with only one force exerted on it.
