Overview
As a pendulum swings, energy converts between potential (at the highest point) and kinetic (at the lowest point). Total energy is conserved (ignoring friction).
💡
Pro Tips
Maximum kinetic energy occurs at the bottom (velocity is highest).
Maximum potential energy occurs at the peak (velocity is zero).
The formula assumes no air resistance or pivot friction.

Fun Facts
"In a perfect vacuum, a pendulum would swing forever, maintaining its total energy."
"The energy of a pendulum is proportional to the mass of the bob."
"Potential energy at height h is mgh; for a pendulum, h = L(1 - cosθ)."
