IB Physics: Course Overview, Study Strategies & Resources
This comprehensive guide offers an in-depth overview of the IB Physics course, addressing its content, structure, and assessment criteria.
| Cuspair | Standard Level (SL) | Higher Level (HL) |
|---|---|---|
| adhbhar | For students with a general interest in physics or those who wish to study the subject as part of a broader scientific education. | For students with a strong interest in physics or those intending to pursue a career or further studies in the field. |
| Cuspairean bunaiteach | Covers a set of core topics that provide a solid foundation in physics. | Shares the same core topics as SL but delves deeper into the concepts. |
| Additional Topics (AHL) | Chan eil gin | Includes more complex concepts and theories in additional higher level (AHL) topics. |
| Teaching Hours | 150 | 240 |
| Structar Measadh | Less demanding assessments, focusing on essential concepts and principles. | More rigorous assessment structure, challenging students to develop a deeper understanding of the subject and refine their problem-solving abilities. |
The IB Physics program is undergoing significant changes in 2023. To read the complete update, check out the IB website. Otherwise, we’ve summarized the key changes, which include:
The physics curriculum is organized into five broad topics, which include:

| Galilean and special relativity (HL only) | Explore the fundamental principles governing the motion of objects at varying speeds, particularly when approaching the speed of light. | Galilean relativity In-variance of the speed of light Time dilation Length contraction Relativistic mass and energy Relativistic momentum |
| Thermal energy transfers | Explore the principles and processes governing the transfer of thermal energy and the behavior of matter under different temperature conditions. | Temperature and thermal energy Heat capacity and specific heat capacity Phase changes Modes of heat transfer Thermal conductivity |
| Buaidh taigh-glainne | Explore the principles, processes, and implications of the greenhouse effect, a key factor in understanding Earth’s climate and global warming. | Greenhouse gases Absorption and emission Earth’s energy balance Climate feedback mechanisms Human activities and the greenhouse effect Climate change and consequences |
Practical work forms an integral part of the IB Physics curriculum, with students dedicating 20 hours for SL and 40 hours for HL to various lab activities. Teachers are encouraged to incorporate practical work into their teaching plans to enhance student understanding and engagement with the subject.
