Repulsion
Definition:
(n.) The act of repulsing or repelling, or the state of being repulsed or repelled.
(n.) A feeling of violent offence or disgust; repugnance.
(n.) The power, either inherent or due to some physical action, by which bodies, or the particles of bodies, are made to recede from each other, or to resist each other's nearer approach; as, molecular repulsion; electrical repulsion.
