 I. Introduction of NEB Physics Syllabus
NEB Physics Syllabus is designed to provide students with an understanding of the scientific laws and principles of the physical world. As expected, this curriculum will provide an opportunity for the students to see  NEB physics as a contribution to life in modern society. The Course demands an emphasis on conceptual understanding of the physical phenomena. This will involve the proper utilization of suitable mathematical models and equations. The applications of NEB physics together with the social and environmental aspects need to be emphasized whenever possible. The students are expected to actively participate in the learning process through experimentation supplemented by demonstration, discussions and problem-solving.

The practical component of this course is designed to supplement learning through the application of the learned theory. The students will handle simple apparatus to do simple measurements, verify physical laws and apply their knowledge of NEB physics to real-life examples.
