PHYSICS
10+1
Senior Secondary stage of school education is a stage of transition from General
education to discipline - based focus on curriculum . The present updated syllabus keeps in
view the rigour and depth of disciplinary approach as well as the comprehension level of
learners . Due care has also been taken that the syllabus is not heavy and is at the same time ,
comparable to the international standards . Salient features of the syllabus include :
 Emphasis on basic conceptual understanding of the content.
 Emphasis , on use of Sl units , symbols , nomenclature of physical quantities and
formulations as per international standards .
 Providing logical sequencing of the units of the subject matter and proper placement of
concepts with their linkage for better learning .
 Reducing the curriculum load by eliminating overlapping of concepts / content within the
discipline and other disciplines .
 Promoting process - skills , problems - solving abilities and applications of Physics
concepts .

Besides , the syllabus also attempts to

 Strengthen the concepts developed at the secondary stage to provide firm foundation for
further learning in the subject .
 Expose the learners to different processes used in Physics - related industrial and
technological applications
 Develop process - skills and experimental observational , manipulative , decision making
and investigatory skills in the learners
 Promote problem solving abilities and creative thinking in learners .
 Develop conceptual competence in the learners and make them realize and appreciate
the interface of Physics with other disciplines .
