A physical system is a system that exists in the real world. It is a collection of physical objects that interact with each other. For example, a car is a physical system.
The main difference between an abstract system and a physical system is that an abstract system does not have a physical implementation, while a physical system does. Abstract systems are often used to model physical systems, but they are not the same thing.
Here are some other key differences between abstract systems and physical systems:
* Abstract systems are typically simpler than physical systems. This is because abstract systems only include the essential features of a system, while physical systems include all of the details.
* Abstract systems can be more easily manipulated than physical systems. This is because abstract systems can be represented mathematically, which makes it possible to perform calculations on them.
* Abstract systems are often used to predict the behavior of physical systems. This is because abstract systems can be used to identify the key factors that affect the behavior of a system, and then use those factors to predict the system's behavior.
Abstract systems and physical systems are both important tools for understanding the world around us. Abstract systems allow us to model and understand complex systems, while physical systems allow us to test our theories and predictions.
