If the motion be that of a material particle , however , there can be no abrupt
change of velocity , nor of direction unless where the velocity is zero , since ( as
we shall afterwards see ) such would imply the action of an infinite force . It is
useful to ...

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 .

8 driving - power to be made , we can evidently obtain an approximation to the
velocity at a particular instant , by considering ( § 25 ) the motion for so short a
time , that during that time the actual variation of speed may be small enough to
be ...

Thus a point moving with velocity V up an Inclined Plane , making an angle a with
the horizon , has a vertical velocity V sin a and a horizontal velocity Vcosa . Or it
may be resolved into components in any three rectangular directions , each ...
