Answer:
It is a law, because it states how force relates to a spring but does not explain why.
Step-by-step explanation:
It is also known as Hooke's law. by the help of this law we can find the relation between force exerted due to spring and the displacement of the one end of spring from its natural length.
This is verified experimentally that how the length of the spring will change and that requires how much force to balance the force due to spring.
So in this experiment we can observe that more force is required to pull or push the spring by more distance.
So here we will say that any description which is verified experimentally but not theoretically then it must be a law.
so correct answer will be
It is a law, because it states how force relates to a spring but does not explain why.
