Here's why:
* Energy Conservation: As the pendulum swings, its energy is constantly being converted between potential energy (at the highest points of its swing) and kinetic energy (at the lowest point).
* Potential to Kinetic: At the highest points, the bob has maximum potential energy and zero kinetic energy (since it's momentarily at rest). As it swings down, potential energy is converted into kinetic energy, causing the bob to speed up.
* Maximum Kinetic Energy: At the bottom of the swing, all the potential energy has been converted into kinetic energy, resulting in the maximum velocity.
* Kinetic to Potential: As the bob swings back up, the process reverses, and kinetic energy is converted back into potential energy.
