AICEE - Physics syllabus

Physics

The syllabus in Physics aims at providing the learners with sufficient conceptual background which would eventually make them competent to meet the challenges of academic as well as professional courses during their corresponding courses after AICEE. Some of the salient features of the updated syllabus are :

  • Emphasis on basic conceptual understanding of the content.
  • Promoting process-skills, problems-solving abilities and applications of basic concepts in real life situations.
  • Emphasis on use of SI units, symbols and formulations as per international standards.
  • Emphasis on Physics-related technological/industrial aspects to meet the changing demand of society.
  • Providing logical sequences of the units of subject matter and proper placement of concepts.
  • Emphasis on inclusion of indigenous knowledge and Indian contribution to Physics and technology.
  • Reducing curriculum load by eliminating overlapping of concepts/content within the discipline.
  • Inclusion of emerging areas such as principals of communication and space/satellite communication.
