In the seventeenth century, robert hooke conducted many experiments with springs. in all the data he recorded, he found that the force needed to push down on a spring or stretch it out from its usual resting point was equal to the spring’s stiffness multiplied by the distance it is pushed or pulled from its resting point. he wrote the equation f = kx, in which f is the force, k is the spring’s stiffness, and x is the distance the end of the spring moves from its usual resting point when no push or pull is applied. the equation is still used today. which best describes hooke’s equation? it is a law, because it explains why a force must be applied to push or pull a spring. it is a law, because it states how force relates to a spring but does not explain why. it is a theory, because it explains why a force must be applied to push or pull a spring. it is a theory, because it states how force relates to a spring but does not explain why.

It is a law, because it states how force relates to a spring but does not explain why.

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.
