Hooke's Law states that within the elastic limit, the force required to stretch or compress an elastic material (like a spring) is directly proportional to its displacement from equilibrium.
Elastic Limit: The maximum amount of deformation an elastic material can undergo and still return to its original shape.
Equilibrium Position: The position where the force on an object is balanced, resulting in no net force or acceleration.
Displacement: The change in position of an object from its initial position.
