Remember that power required to push air out of the way is quadratic with speed. The 10 mph increase here is a 30% increase in kinetic energy in any given crash

- sdinsn 7y agoYou are right that kinetic energy scales quadratically, but it have nothing to do with "pushing air". The kinetic energy formula is the same in a vacuum.
