Two examples of physical systems designed by people are:

1. Air conditioning system: Air conditioning systems are designed to control and regulate the temperature, humidity, and ventilation in indoor spaces. They typically consist of several components, including a compressor, condenser, evaporator, and a network of ducts or pipes to distribute the conditioned air. People design these systems to create a comfortable and controlled environment, particularly in places with extreme climates.

2. Transportation system: A transportation system is a network of infrastructure, vehicles, and operating protocols designed to facilitate the movement of people, goods, and services. This includes roadways, railways, airports, seaports, and various modes of transportation like cars, trains, airplanes, and ships. People design transportation systems to efficiently connect different locations, enabling the smooth flow of passengers and cargo.

To design physical systems like these, engineers and designers analyze requirements, consider factors such as efficiency, safety, and usability, and employ principles of physics, materials science, and other relevant fields. They use this knowledge to create plans, schematics, and prototypes that are then implemented in the construction and manufacturing processes.
