"Squared" means you take the number it's attached to ... including the unit ... and
multiply the whole thing by itself. For example, when you take inches of length and
square it, you get inches squared of area.
(Miles per hour) squared doesn't have any obvious physical significance, but when you
multiply that by mass, and massage the result just a little, you have familiar, everyday
units of energy.
