Spring Constant (k):The spring constant measures how stiff or soft a spring is. It determines how much force is required to stretch or compress the spring.
Displacement (x):Displacement refers to how far an object has moved from its equilibrium position. In this context, it represents how much a spring is stretched or compressed.
Potential Energy (U): Potential energy is stored energy that an object possesses due to its position or condition. In this case, it refers to the energy stored in a compressed or stretched spring.
