Simple Harmonic Motion and Equilibrium

Your entire life is basically just a struggle to get back to equilibrium. That is the whole

point of Simple Harmonic Motion. Whether it’s a guitar string or a kid on a swing,

the physics is identical. The rule is super specific: the further you move away from the center,

the harder the acceleration pulls you back. It’s a literal tug-of-war. And the energy transfer is wild.

You are constantly swapping potential energy at the edges for maximum speed in the middle.

You never actually lose energy, you just keep trading it back and forth until friction ruins

the party.
