Hooke's Law states that the force needed to extend or compress a spring by some distance is proportional to that distance.
F = -k × x
- F (Force): The restoring force exerted by the spring (Newtons).
- k (Spring Constant): A measure of the spring's stiffness (N/m).
- x (Extension): The distance the spring is stretched or compressed from its equilibrium (meters).
