That's not a valid comparison; one involves changing the object's potential
energy(basically, its height*mass.)  The other is changing its velocity,
which requires an initial change in kinetic energy(velocity*mass) and then
countering air, rolling, and mechanical(engine/drivetrain) friction.

Egad.  You've heard of LDS flashbacks; I just had a late-nite Physics
flashback :o
