k (spring constant): The spring constant represents the stiffness or rigidity of a spring. It determines how much force is required to stretch or compress the spring by a certain distance.
A (amplitude): Amplitude refers to the maximum displacement or distance from equilibrium that an object experiences during oscillation.
Potential Energy:Potential energy is the stored energy possessed by an object due to its position or condition. In this case, Umax represents the maximum potential energy stored in a system.
