IB Diploma Physics

Physics is the most fundamental of the experimental sciences, as it seeks to explain the universe itself from the very smallest particles. Newtonian mechanics, electromagnetism and thermodynamics help to understand the universe. However, Newtonian mechanics did not work when applied to the atom. Most of the atomic structure has been explained by quantum mechanics. The IBDP Physics syllabus includes the essential principles of physics from simple mechanics to complex quantum mechanics. This course provides full coverage of the IB Diploma syllabus in Physics and offers support to students preparing for their examinations. In this course, teachers will provide examples and exam tips that demonstrate best practices and warn against common errors. Modules were prepared for each topic to navigate students through the content and essential ideas.
