Senior Secondary Course (Syllabus)
Physics

RATIONAL
Physical is a fundamental science because it deals with such basic feature of the world as time, space, motion matte, electricity, light and radiations. Every event that occurs in the natural world has some feature that can be viewed in these terms. Study of Physics need not necessarily be taken as means of becoming a physicist; it is a means of rationally understanding nature. Physics lies behind all technological advancement such as computer, internet, lunching of rockets and satellites, radios and TV communications, lasers, etc. It also finds applications in such simple activities of men as lifting a heavy weight or making a long jump. Physics is thus an all-pervading science and its study helps us in finding answers to questions like why and how?

In order to bring out various aspects of Physics as a fundamental science the content of the present syllabus has been so chosen as to relate with the study of natural physical phenomenon. The underlying physical laws and principles of such phenomena and their effects on daily life have been reflected in the syllabus. Themes like motion, properties of matter, energies like heat, light and electricity and electronics with would be of interest to all and specially to those who are interested in pursuing Physics as a career have been selected to from our content. The syllabus also includes such emerging areas as electronics, nuclear physics, astrophysics, medical physics and photography, which find immense applications in daily life.

Though mathematics is basic to the understanding of most of the problems of physics, in the present course stress has been given to avoid rigour or mathematics like integration and differentiation. The focus has been to teach concepts of physics rather than mathematics calculation.
This course attempts.

  1. acquire knowledge and develop understanding of concepts, fundamental laws, principles and processes in the area of physics so that relationship between cause and effects of physical phenomenon can be understood;
  2. appreciate the contributions of physics towards improving quality of lice;
  3. promote interest in physics and foster a spirit of enquiry; and
  4. Improve competencies of individuals in work skills required in their procession.

As a part of this process, the course also aims at developing the following abilities in the learner:

  • Experimental skills (like taking observations, manipulation of equipment) and communicative skills such as reporting of observations and experimental result;
  • Problems solving ability e.g. analyzing a situation or data, establishing relationship between cause and effects:
  • Scientific temper of mind by making judgment on verified facts and not opinions, by showing willingness to accept new ideas and discoveries: and
  • Awareness of the dangers inherent in the possible misuse of scientific knowledge.

Structure of the Syllabus
The syllabus in physics includes two parts-core modules and optional modules. The core modules comprises of the essential concepts and phenomenon of physics, which a student at this level should know. It has eight core modules, which contain predominantly the subject matter of mechanics, electricity, light and other areas of physics representing the minimum knowledge required to progress into the more advanced areas and to develop appreciation for the fact that physics plays a significant role in most situations. The optional modules are on the specific fields and have four modules one each on Astrophysics, Electronics, Photography and Audio-Videography and Medical physics. In the optional modules there is a choice to opt any one of the given four modules.
