Energy Stored On Spring

(kx^2)/2

Resonance

When the driving frequency approaches the natural frequency, the system gains more and more energy from the driving force and so vibrates with a rapidly increasing amplitude.

Damping

Energy lost to the surroundings, usually down to frictional forces, which minimises the effect of resonance.
