During the operation of a pendulum, what happens at the lowest point of its swing?

At the lowest point of a pendulum's swing, kinetic energy is at its maximum due to the principles of energy conversion in a pendulum system. When the pendulum is released from a height, it possesses gravitational potential energy, which is highest at the peak of the swing. As the pendulum moves downward, this potential energy gradually converts into kinetic energy, reaching its peak at the lowest point of the swing.

At this lowest point, the pendulum's speed is greatest as it has just converted nearly all of its potential energy into kinetic energy, allowing it to swing upward again. Therefore, at this position, the kinetic energy is maximized, enabling the pendulum to continue its motion and rise to the opposite height. This dynamic highlights the conservation of mechanical energy, where total energy remains constant, and energy shifts between potential and kinetic forms.
