Steve Mould made a video called "The Lever Paradox" (link below).
In that video, he highlights some unintuitive behavior with simple levers, but he didn't show the math behind why that happens.
In this video, we'll show that math.

We'll show what "mechanical advantage" means and why that happens.
We'll show that levers conserve kinetic energy in the form of work.
