When a point moves from one position to another it must evidently describe a
continuous line , which may be curved or straight , or even made up of portions of
curved and straight lines meeting each other at any angles . If the motion be that

As two successive positions of it contain the second side of the polygon above
mentioned , it is evident that the osculating plane passes from one position to the
next by revolving about the tangent to the curve . 13. Thus , as we proceed along

... by different points of the string ; and these will , in general , be different curves .
But the following section shows that there is but one evolute . 22. Let AB be any
curve , PQ a portion of an involute , pP , qe positions of the free part of the string .

The rate of motion of a point , or its rate of change of position , is called its
Velocity . It is greater or less as the space passed over in a given time is greater
or less : and it may be uniform , i.e. the same at every instant ; or it may be
variable .
