In the real world, a pendulum would eventually come to a stop due to the presence of external factors and forces that are not accounted for in this closed system simulation. These external factors could include air resistance, friction at the pivot point, and the conversion of mechanical energy into other forms of energy such as heat or sound.
Air resistance plays a significant role in slowing down a pendulum's motion. As the pendulum swings back and forth, it encounters air molecules that create resistance and dampen its movement. Over time, the cumulative effect of this resistance would gradually decrease the amplitude of the pendulum's swing until it eventually comes to rest.
Friction at the pivot point is another factor that would contribute to the pendulum's eventual stoppage in the real world. As the pendulum swings, the pivot point experiences friction due to the contact between its components. This friction causes a loss of mechanical energy, which translates into a reduction in the pendulum's motion until it ceases to swing.
Finally, the conversion of mechanical energy to other forms of energy also leads to the eventual stoppage of a pendulum in the real world. As the pendulum swings, it loses energy through processes like air resistance, friction, and the generation of heat or sound. This energy loss reduces the pendulum's overall motion and gradually brings it to a stop.
Therefore, in a real-world open system, a pendulum would eventually stop due to the presence of factors such as air resistance, friction at the pivot point, and the conversion of energy into other forms. These factors are not considered in the closed system simulation, resulting in the perpetual motion of the pendulum.
Continue to play the simulation. This simulation will go on and on for eternity if we let it. This simulation is in what we call a Closed System. We are only looking at the variables we want to in this simulation. In the Real World (Open System), if we had a Pendulum like this, it would eventually stop. Explain why it would stop in the Real World.
