📖 The Unstoppable Truck

A tennis ball at 50 m/s is annoying. A truck at 50 m/s is deadly. Same speed, VERY different momentum. Momentum combines mass AND velocity — it's the "oomph" of moving objects. Here's the beautiful thing: momentum is ALWAYS conserved. In any collision or explosion, total momentum before = total momentum after. This lets us predict what happens when things crash, from snooker balls to cars to galaxies colliding!
