H1 Physics and H2 Physics are both core subjects in the Junior College (JC) curriculum in Singapore. H2 Physics is a more advanced version of H1 Physics, and covers a wider range of topics and requires a higher level of physics proficiency.

H1 Physics covers the basics of physics, including mechanics, thermal physics, waves, optics, and atomic physics. H1 Physics is suitable for students who want a general understanding of physics but do not intend to pursue a career in a field that requires advanced physics knowledge.

H2 Physics, on the other hand, covers all the topics in H1 Physics in greater depth, and also covers additional topics such as electromagnetism, quantum physics, and nuclear physics. H2 Physics is recommended for students who intend to pursue a degree in fields such as engineering, physics, or astronomy, as it provides a strong foundation in the advanced physics concepts required for these fields.

The main difference between H1 Physics and H2 Physics is the level of depth and complexity. H2 Physics requires a higher level of physics proficiency, and covers more topics than H1 Physics. H2 Physics is also a more demanding subject, with a greater workload and higher expectations in terms of problem-solving and critical thinking skills.

In terms of university admissions, most university courses require at least H1 Physics, while some courses require H2 Physics. Therefore, it is recommended that students take H2 Physics if they are considering pursuing a degree in a field that requires advanced physics knowledge. However, it is important to note that H1 Physics is still a valuable subject that provides a good foundation in physics, and can be suitable for students who are not planning to pursue a career in a field that requires advanced physics knowledge.
