In physics , the force with which bodies remain attached to each other when brought into contact; e.g. , ink adheres to paper, paint adheres to wood, . It differs from ‘cohesion’ in representing the force with which different bodies cling together; whereas cohesion is the force which unites the particles of a homogeneous body with each other, e.g. , particles of iron cohere and form a ma of iron; particles of water cohere and form a ma of water, .
