[Part 5] Why Landslides GROW As They Fall (Physics of Entrainment) 🪨

A catastrophic landslide isn't just a pile of rocks moving from point A to point B—it's a growing, evolving monster that "eats" the mountain! 🏔️⚠️ Discover the terrifying physics behind "Entrainment." As a moving mass rips through a mountain valley, it erodes the earth, swallowing loose sediment, rocks, trees, and water. While picking up new material actually consumes energy and might not make the flow faster immediately, it massively increases the total mass, momentum, and destructive impact forces. 🌊🪨 By the time it reaches the bottom, the disaster has transformed into a completely different, unstoppable beast. This complex fluid dynamics behavior is exactly why a single speed or simple friction coefficient can't explain a mega-disaster! 👇 What surprised you the most about the physics of this natural disaster?
