attraction .]
1 . (
Physics )
An invisible power in a body by which it draws anything to itself ;
the power in nature acting mutually between bodies or ultimate particles ,
tending to draw them together ,
or to produce their cohesion or combination ,
and conversely resisting separation .
[
1913 Webster ]
Note :
Attraction is exerted at both sensible and insensible distances ,
and is variously denominated according to its qualities or phenomena .
Under attraction at sensible distances ,
there are , -- (
1 .)
{
Attraction of gravitation },
which acts at all distances throughout the universe ,
with a force proportional directly to the product of the masses of the bodies and inversely to the square of their distances apart . (
2 .)
{
Magnetic }, {
diamagnetic },
and {
electrical attraction },
each of which is limited in its sensible range and is polar in its action ,
a property dependent on the quality or condition of matter ,
and not on its quantity .
Under attraction at insensible distances ,
there are , -- (
1 .)
{
Adhesive attraction },
attraction between surfaces of sensible extent ,
or by the medium of an intervening substance . (
2 .)
{
Cohesive attraction },
attraction between ultimate particles ,
whether like or unlike ,
and causing simply an aggregation or a union of those particles ,
as in the absorption of gases by charcoal ,
or of oxygen by spongy platinum ,
or the process of solidification or crystallization .
The power in adhesive attraction is strictly the same as that of cohesion . (
3 .)
{
Capillary attraction },
attraction causing a liquid to rise ,
in capillary tubes or interstices ,
above its level outside ,
as in very small glass tubes ,
or a sponge ,
or any porous substance ,
when one end is inserted in the liquid .
It is a special case of cohesive attraction . (
4 .)
{
Chemical attraction },
or {
affinity },
that peculiar force which causes elementary atoms ,
or groups of atoms ,
to unite to form molecules .
[
1913 Webster ]
2 .
