In theory a pulley is simply a smooth body which changes the direction of a
flexible and inextensible cord stretched across part of its surface ; in practice ( to
escape as much as possible of the inevitable friction ) it is a wheel , on part of

Force is wholly expended in the Action it produces ; and the body , after the force
ceases to act , retains by its inertia the direction of motion and the velocity which
were given to it . Force may be of divers kind , as pressure , or gravity , or friction ...

A curling - stone , projected along a horizontal surface of ice , travels equal
distances , except in so far as it is retarded by friction and by the resistance of the
air , in successive intervals of time during which the earth turns through equal
angles .

... resistance be measured by the velocities of its several parts into their several
forces , whether these arise from friction , cohesion , weight , or acceleration ; --
action and reaction , in all combinations of machines , will be equal and opposite
.

But in Newton's day , and long afterwards , it was supposed that work was
absolulely lost by friction ; and , indeed , this statement is still to be found even in
recent authoritative treatises . But we must defer the examination of this point till
