Скачать или смотреть General Physics 1: Lecture: Newton's Third Law - Action, Reaction, and Interaction Pairs

In this lecture, we explore Newton’s Third Law, which states that every force occurs as part of an interaction pair: for every action, there is an equal and opposite reaction. We examine how these forces act on different objects, how to identify them in real-world situations, and why understanding interaction pairs is essential for solving dynamics problems.

Key Concepts
• Newton’s Third Law: action-reaction symmetry
• Identifying interaction pairs
• Forces always come in equal and opposite pairs
• Everyday examples — walking, pushing objects, collisions
• How Third Law forces relate to free body diagrams
