Picture a bowling ball rolling slowly down a hill. Now picture a feather drifting the same speed. One of them you'd happily catch with your bare hands. The other you would absolutely not. Same speed wildly different "please don't." That stubborn "keep going" feeling stuff has when it's moving? That's momentum.

Momentum is a deal between two things: how heavy you are, and how fast you're going. Multiply them together and you get how much "oomph" is barreling forward. More mass, more momentum. More speed, more momentum. It's that simple — and that's what makes it so beautifully bossy.
