The total energy in simple harmonic motion is the sum of its potential energy and kinetic energy. We seek here the equation that relates the position of the mass as a function of time (with the equilibrium point being the origin), usually referred to as the equation of motion for this force. What this means is that the spring mass system is a typical simple harmonic motion as the acceleration is directly proportional to the negative of the displacement (extension). ω = √g/l. You may be asked to prove that a particle moves with simple harmonic motion. 1 Simple Harmonic Motion We will now go on to examine how the conservation of energy can be used to solve the equations of motion for an oscillating diatomic molecule.
