Understanding Energy Conservation in Pendulums

The video tutorial explains the application of the law of conservation of energy using a simple pendulum. It describes how energy is transformed between potential and kinetic forms during pendulum motion. At extreme positions, the pendulum has potential energy, while at the equilibrium position, it has kinetic energy. The total energy remains constant throughout the motion, illustrating the conservation of energy principle.
