The CBSE Class 11 and 12 Physics syllabus covers a wide range of topics from mechanics and thermodynamics to optics and modern physics. Class 11 focuses on fundamental concepts like motion, forces, energy, and properties of matter, while Class 12 delves into electricity, magnetism, optics, and the quantum world. Both classes include practical components with experiments and activities.

Unit I: Physical World and Measurement: Introduces the concept of physical world, measurement, units, and dimensions. 

Unit II: Kinematics: Deals with motion in a straight line and in a plane, including displacement, velocity, and acceleration. 

Unit III: Laws of Motion: Focuses on Newton's laws of motion, inertia, friction, and circular motion. 

Unit IV: Work, Energy, and Power: Covers work, kinetic and potential energy, power, and the work-energy theorem. 

Unit V: Motion of System of Particles and Rigid Body: Explores center of mass, momentum, torque, and rotational motion. 

Unit VI: Gravitation: Covers Kepler's laws and Newton's law of universal gravitation. 

Unit VII: Properties of Bulk Matter: Explores elasticity, stress, strain, and elastic moduli of solids. 

Unit VIII: Thermodynamics: Deals with the first law of thermodynamics, heat transfer, and various thermodynamic processes.
