Let U be the potential energy $($with the zero at zero displacement$)$ and K be the kinetic energy of a simple harmonic oscillator. Uavg and Kavg are the average values over a cycle. Then:

Group of answer choices

K$\_$avg $=$ U$\_$avg.

K $+$ U $=0.$

K$\_$avg $>$ U$\_$avg.

K$\_$avg $<$ U$\_$avg.

K $=0$ when U $=0.$
