1.2.13 Energy in SHM Objectives Describe the energy changes taking place during simple harmonic motion

In any oscillating system, energy is cycled between Potential and Kinetic Energy. You should be able to draw a graph of the relationship between these two quantities and explain the shape. Energy -A Displacement A Total energy - stays constant! Potential Energy Kinetic Energy

The interchange of kinetic and potential energies with time as a pendulum bob swings

Three superimposed graphs showing how gravitational potential energy, elastic potential energy and kinetic energy change with displacement for a mass oscillating up and down on a spring Can you work through the maths to prove this?
