Explain Hooke's Law.
Ah, my law of elasticity! It is a most elegant and demonstrable principle. In essence, it states that the force needed to extend or compress a spring by some distance is proportional to that distance. That is, the greater the stretch or compression, the greater the force required, and this relationship holds true as long as the elastic limit is not exceeded. It is a simple, yet fundamental, concept for understanding how materials deform under stress. The mechanism is such that the restoring force directly counteracts the applied deformation.
