Grade 12 Physics

The Grade 12 physics curriculum is organised into five units: Mechanics, Heat and Thermodynamics, Wave and Optics, Electricity and Magnetism, and Modern Physics. In the Mechanics unit, students engage with three foundational chapters that establish their core understanding of Rational Dynamics, Periodic Motion, and Fluid Statics.  

Transitioning to Heat and Thermodynamics, two chapters delve into the First Law of Thermodynamics and the Second Law of Thermodynamics. Wave and Optics encompass eight chapters, progressing from fundamental principles to a mathematical exploration of Wave Motion, Mechanical Waves, Waves in Pipes and Strings, Acoustic Phenomena, the Nature and Propagation of Light, Interference, Diffraction, and Polarisation. 

The curriculum culminates in the Electricity and Magnetism unit, which covers six chapters focusing on Electrical Circuits, the Thermoelectric Effect, Magnetic Fields, Magnetic Properties of Metals, Electromagnetic Induction, and Alternating Current. The final unit, Modern Physics, comprises six chapters that establish an understanding of Electrons, Photons, Semiconductor Devices, Quantization of Energy, Radioactivity and Nuclear Reactions, and Recent Trends in Physics. 

Through this structured curriculum, students gain a comprehensive grasp of physics, from classical mechanics to cutting-edge modern physics concepts. This educational journey equips them with the knowledge and skills needed to navigate the complex and fascinating world of physics. And also, empowers students to understand and appreciate the natural world and the physical phenomena that govern it.
