Reminder: Kinetic Energy = ½mv^2
Squaring numbers can make them big in a hurry.

- eternauta3k 3y agoNitpick: squaring makes numbers greater than 1 bigger, and numbers smaller than 1 smaller. In this case we're squaring something with units, and we can't say the input is greater or smaller than the output, because they have different units. What we can say, is that v^2 curves upward: it grows faster with increasing v, and slower with decreasing v.
