CBSE Syllabus of Class 11th PHYSICS 2022-2023:

In class 11 CBSE, students will study the basics of physics, including mechanics, thermodynamics, waves, and optics. The class will begin with an introduction to units and measurements, including the International System of Units (SI). This will be followed by kinematics, which deals with the motion of objects and their properties, such as displacement, velocity, and acceleration.
