Force is recognized as acting in two ways : I ° so as to compel rest or to prevent
change of motion , and 2 ° so as to produce or to change motion . Dynamics ,
therefore , is divided into two parts , which are conveniently called STATICS and
...

Hence , just as in § 38 a uniform acceleration , acting perpendicularly to the
direction of motion of a point , produces a change in the direction of motion , but
does not influence the velocity ; so , if a body be rotating about an axis , and be ...

It has been shown already in what sense the term ' point ' is to be taken , and ,
therefore , in what way a force may be imagined as acting at a point . In reality ,
however , the place of application of a force is always either a surface or a space
of ...

According to this principle , the standard or unit force is that force which , acting
on a national standard unit of matter during the unit of time , generates the unit of
velocity . This is known as Gauss ' absolute unit ; absolute , because it furnishes a

Our present application is , that the force of gravity at Edinburgh is 32.2 times the
force which , acting on a pound for a second , would generate a velocity of one
foot per second ; in other words , 32.2 is the number of absolute units which ...
