And, how would you find out how it varies according to a variable?

I'm quite confused bout this and i need some help on how to even start!

you could investigate the energy conversions involved in a mass oscillating on a spring. There are three types of energy involved, K, the kinetic energy of the mass, Us the potential energy of the spring and Ug the gravitational potential energy of the mass. By using the SHM equations and measuring the spring constant of the spring you can calculate K at say five points during it's oscillation, the midpoint, the end points and at two other displacements on both sides of the equilibrium. Plot these points as a function of the displacement and draw a smooth graph through them. Also calculate and draw such graphs for the other two forms of potential energy - maybe by taking the zero potential energy at the equilibrium position of the mass. By adding the three graphs up you should then get a constant energy graph. E = K + Us + Ug proving that energy is conserved in this system. In this system energy is transferred from one part to the other and back again. Also it varies according to the displacement of the mass w.r.t. the equilibrium position.
