The very first concept of physics study is the
recognition of the physical system. Proper selection of the system can be
deemed as half of the work done during an analysis. This article tries to gain
further insight on this very important element of scientific thinking.
The
Physical System and the Its Environment:
- · The choice of the physical system is vital to the success of any analysis or problem solving.
- · Depending on the objective of study, the entire process of scientific thinking commences with the identification of this element.
- · Precision in the choice of the physical system reduces the complications in the study.
- · The system can either be a part of an object, the entire object or certain external objects surrounding the main object taken together as a whole.
- · Once the system is chosen or identified, everything else surrounding it, technically form the environment.
- · The system can be studied as a separate entity or can be treated along with its surrounding.
- · In the former case, the study is that of an isolated system and in the latter case, the system is said to be non-isolated.
- · Awareness of the objective of the study proves vital in the proper selection of the physical system and in the distinction of its environment.
- · The choice of the physical system should be such that the process of analysis becomes simple and yet retains relevance.
- Conclusion: Initially, the choice of the physical system does involve trial and error. But, with experience the identification of the system becomes obvious and happens instantaneously.
