Ascientific law is something we can use to make a specific, concrete prediction. for example, the law of gravitation states that masses will attract each other, and you will find that this is always the case. however, it can also be used to make concrete statements about the properties of an object in the right conditions. for example, if a material were found that was not attracted to other objects with masses, we could say that a) the material is charged. b) the material has no mass. c) the material must be floating. d) the material has very little mass.
