[[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.
