Horse Power and its Effectiveness

[Mike Rolica]

More thatn gravity, even without gravity you have the inertia of the mass of
the car. One of newtons laws! Oject will remain at steady state of motion
until acted upon by an unbalaced force.  But for every action ther is an
equal and opposite reaction.  Push the car ahead, you will have a force push
back......Inertia force.

	For the hands on type guys, I read that the astronauts fixing the
	Hubble had trouble with some bolts.  Seems that a small twist CCW
was
	enough for a bolt to slowly unscrew and begin to float away.
Imagine
	the time saver if you could start all the bolts in your intake
	manifold unscrewing themselves while you head off to call the parts
	store.
