About Moment of Inertia
Moment of inertia measures how hard something is to spin up, and it depends on where the mass sits rather than just how much there is. Move mass twice as far from the axis and the moment of inertia quadruples, because the distance is squared. That's why a skater spins faster with their arms pulled in, and why flywheels carry their weight at the rim. The SI unit is the kilogram square metre.
