The physics section mainly focuses on mechanics and electricity for semester two. The content covers most high school physics, university physics, IB physics (SL and HL), AP Physics 1, and AP Physics 2. Because different curricula have different syllabus, some topics are mixed. For example, electric and magnetism for IB Physics includes electric potential. Ohm’s law is another topic. These are set as independent topics for some curricula and universities. Most contents are the same in introductory physics courses. They are arranged in different orders. This website should work most for AP, IB, and high school students. Hope you find this website helpful and keep up with physics!!!
