PHYSICS - Forces - Newton's 3rd Law of Motion

The video explains Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. It provides examples such as a swimmer pushing against a pool wall, a person sitting on a chair, and a book moving across a table. The video also discusses rocket propulsion and rifle recoil, highlighting how forces come in pairs and the relationship between force, mass, and acceleration. The concept of action-reaction pairs is illustrated through various scenarios, emphasizing the equal magnitude and opposite direction of forces.
