GPT 3.5
If we neglect friction, the total mechanical energy of the pendulum remains constant.
The total mechanical energy of a pendulum is the sum of its kinetic energy and potential energy. As the pendulum swings, it moves between potential energy (when it is at the highest point of its swing) and kinetic energy (when it is at the lowest point of its swing). At the highest point, the pendulum has its maximum potential energy, and at the lowest point, it has its maximum kinetic energy.
In the absence of friction or any other external forces, the total mechanical energy is conserved throughout the pendulum's motion. This means that as the pendulum swings back and forth, its potential energy and kinetic energy interchange, but the sum of these energies remains constant.
However, in real-world scenarios, there is always some amount of friction present, which causes the dissipation of energy in the form of heat. As a result, the total mechanical energy of the pendulum gradually decreases over time, causing the pendulum to eventually come to a stop.
