Why objects don't just pass through each other
In short: You can't touch something without feeling a force. This video explores the invisible physics of contact forces, revealing how everyday interactions like friction and tension are actually governed by the behavior of atoms.
Paul Andersen breaks down common physical interactions—including normal, applied, friction, tension, spring, and buoyant forces—by looking at their origins. Rather than treating these as abstract concepts, the video explains how they emerge from interatomic forces.
Understanding these mechanics provides a deeper look at why matter behaves the way it does. By examining the microscopic level, we can better comprehend the macroscopic world of motion and resistance.
