Elastic Potential Energy

Hooke's Law: Hooke's Law states that the force needed to stretch or compress an elastic object is directly proportional to the displacement from its equilibrium position.

Spring Constant: The spring constant (k) represents how stiff or soft a spring is. It determines how much force is required to stretch or compress the spring by a certain amount.

Conservation of Mechanical Energy: This principle states that in an isolated system where only conservative forces are acting, the total mechanical energy (kinetic + potential) remains constant.
