the difference between compression and tension is that a compressing force causes an object to shorten in the direction of the force, while a tension force causes an object to lengthen in the direction of the force. regardless of the strength of the material, compression and tension forces always cause some amount of deformation. different materials deform in different amounts and return to their .read more≫

liquid compression is difficult but not impossible because they feature a mid-level intermolecular force that makes their molecules difficult to compress. intermolecular force is the strength used to hold molecules tightly together or force them apart. the strength of the intermolecular force depends on the state of the matter, with solids having the strongest intermolecular force and gases having.read more≫
