Problem 5: Consider a 1D simple harmonic oscillator (without damping). (a) Compute
the time averages of the kinetic and potential energies over one cycle, and show that they
are equal. Why does this make sense? (b) Show that the space averages of the kinetic and
potential energies are
(T)₂ = k1²
KA² and (U),= KA².
Why is this a reasonable result?
True or False and please explain why:
In a simple harmonic oscillator without dissipation (friction, drag, resistance, etc.) the energy is conserved.
Calculate the energy, corrected to first order, of a harmonic oscillator with potential:
