Rationale and Objectives

 

Knowledge of Physics is so interwoven with engineering studies that one can not think of pursuing engineering studies without the knowledge of Physics. Study of Physics is essential for Diploma holders in engineering and technology to develop in them proper understanding of physical phenomenon, scientific temper and engineering aptitude.

The course covers the basic laws and principles of Physics and its applications. The course contents are so chosen that it should be more relevant to the modern development of science to meet the challenge posed by fast-changing technology.

 

Keeping these objectives in view the subject has been divided into the following topics:

 

 CURRICULUM
SL Topics Periods
1. General Physics 22
2. Heat 01
3. Electrostatics 03
4. Current, Electricity and Magnetism 12
5. Modern Physics 10

Teachers are advised to use the latest technology of teaching (e.g. use of LRs etc.) and make maximum use of demonstration so that the subject will be interesting to the students. The Engineering applications of the principles of physics should be discussed broadly. Use of S.I. units for all measurements and calculations is recommended.
