Physics - SHM Question with Solution | TestHub

Total energy =   $\mathrm{P} \mathrm{E} + \mathrm{K} \mathrm{E}$.

When a particle executes SHM, there is one position between maximum amplitude and mean position where $\mathrm{PE}$ is equal to $\mathrm{KE}$, and particle have to cross that point four times to complete one oscillation.
