Spring Force: The force exerted by a spring when it is stretched or compressed. It follows Hooke's Law and is directly proportional to the displacement of the spring.
Spring Constant:A measure of how stiff or flexible a particular spring is. It represents the ratio between the force applied to a spring and its resulting displacement.
Elastic Potential Energy:The energy stored in an elastic object (such as a stretched or compressed spring) due to its deformation from its equilibrium position. It depends on both the displacement and stiffness of the object.
