When a point moves from one

**position**to another it must evidently describe acontinuous 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

The rate of motion of a point , or its rate of change of

Velocity . It is greater or less as the space passed over in a given time is greater

or less : and it may be uniformi , i.e. the same at every instant ; or it may be

variable .

The rate of motion of a point , or its rate of change of

**position**, is called itsVelocity . It is greater or less as the space passed over in a given time is greater

or less : and it may be uniformi , i.e. the same at every instant ; or it may be

variable .
