Why every interaction creates a pair of equal and opposite forces

Action and reaction forces | Movement and forces | Middle school physics | Khan Academy · 4:52 · Video: Khan Academy · Watch at the source

In short: This video explores the fundamental principle of interaction: whenever two objects exert force on one another, they do so with equal strength but in exactly opposite directions.

The video examines the mechanics of how objects interact. It explains that forces do not exist in isolation; rather, whenever an interaction occurs between two objects, a pair of forces is generated. These forces are characterized by being equal in magnitude while acting in opposite directions.
