In simple harmonic motion, the total energy of the particle is constant at all instants which are totally kinetic when the particle is passing through the mean position and is totally potential when the particle is passing through the extreme position.

The variation of PE and KE with time is shown in the figure, by the dotted parabolic curve and solid parabolic curve respectively.
Figure indicated that maximum values of total energy KE and PE of SHM are equal.

therefore, (EK)max = Ko
So, (EP)max = Ko
and (E)Total = Ko
