Oscillations In an ideal SHM, total mechanical energy stays constant. Kinetic energy peaks at equilibrium, potential peaks at turning points.
Summary
- Total mechanical energy in an SHM =
E_{total}=U+K - Spring-object system:
E_{total}=\frac{1}{2}kA^2 - Real systems lose energy to friction and such, lowering oscillation over time.
