WBCHSE Class 11 Physics Syllabus

Physics is the most motivating subject, which is full of wonders. This subject requires a lot of brain work, as it mainly deals with the study about the measurements, different laws of Newton’s, etc. The class 11 physics syllabus provided here help students to prepare for their exam more effectively. The important topic for class 11 physics includes – Laws of Motion, Behaviour of perfect gas and kinetic theory of gases, thermodynamics, heat transfer, Physical world and the measurements and lot more.

We at BYJU’S provide the syllabus for WBCHSE Class 11 Physics along with the mark-wise weightage for every chapter, so that students can have a good idea about the pattern of the exam.
