Energy in an Oscillation or a Wave A simple oscillation is described by the following equation: Where A is amplitude, t is time and  ,  are constants.Consider an object of mass m hanging on a spring. Its potential energy, resulting from the contraction or the dialation of the spring would be:  Once, it starts to move, its kinetic energy would be:  From the Law of conservation of mechanical energy, the sum of the two forms of energy is the total energy.  Since the potential energy has its maximum value and the kinetic energy its minimum when the mass reaches height of the amplitude,  The total energy of a simple oscillation is proportional to the square of its amplitude. Electric Charge Energy  Where V is electric potential or voltage, Q is charge and C is . If a charge dq is positioned between two parellel plates with opposite charge of Q, its partial potential energy would be:  |
