What Does IB Physics Cover?
IB Physics covers an extraordinary breadth of topics, from classical mechanics and thermodynamics to waves, electromagnetism, nuclear physics and, at Higher Level, further optics, quantum physics and engineering physics. The course develops both theoretical understanding and practical scientific skills, with a strong emphasis on data analysis, error propagation and experimental design. Physics is widely regarded as one of the most demanding IB subjects, but also one of the most rewarding — it opens doors to engineering, medicine, computer science and virtually every STEM pathway at university.
What Makes IB Physics Challenging?
IB Physics is challenging because it requires students to integrate mathematical skills with physical intuition. Many students can recall formulas but struggle to set up problems correctly, identify which principles apply and carry out multi-step reasoning under exam pressure. At Higher Level, the additional topics demand significant mathematical confidence, particularly in calculus-based approaches. The Internal Assessment — a hands-on experimental investigation — requires careful planning, rigorous data collection, proper uncertainty analysis and a well-structured scientific report that meets all IB criteria.
How Does Pietro Work on IB Physics?
As a PhD in Physics with research experience in the United States, I bring a depth of subject knowledge that goes far beyond the IB syllabus. This allows me to explain concepts with real-world context and scientific rigour while keeping lessons accessible and engaging. I help students develop physical intuition — the ability to visualise what is happening in a problem before reaching for equations. We work extensively with past papers, learning how to decode mark schemes and structure answers for maximum marks. For the Internal Assessment, I provide step-by-step guidance on experimental design, data processing and scientific writing.
Common Challenges
Translating word problems into equations and identifying which physical principles to apply
Mastering uncertainty analysis and error propagation in experimental work
Connecting mathematical tools (calculus, vectors) to physical situations at HL
Designing a rigorous and original Internal Assessment experiment
Managing time effectively across Paper 1, Paper 2 and Paper 3 in the final exams
Strategies for Success
Always start by drawing a diagram and identifying the known and unknown quantities before writing equations
Practise past papers under exam conditions and study the mark schemes to learn how points are awarded
Build a personal summary of key equations, definitions and linking concepts for each topic
For the IA, choose an experiment you can actually perform well and that yields quantifiable, graphable data
Frequently Asked Questions
What is the hardest part of IB Physics?▾
Setting the problem up, not solving it. Choosing which principle applies and turning a worded situation into equations is where most marks are lost, and at Higher Level the extra topics also demand real mathematical confidence.
How important is uncertainty analysis in IB Physics?▾
It runs through the whole course. Data analysis, propagation of uncertainty and evaluation appear in the written papers and sit at the centre of the internal assessment, and it is the skill students most often arrive without from IGCSE or MYP.
Should I take Physics at HL or SL?▾
Take HL if you are applying to engineering, physics or a competitive STEM degree that names it, since many do. SL is accepted for most other courses. Check the specific programme pages in the first Diploma year, because moving up a level later is very difficult.
Physics is my field of research and my greatest passion. I know what it takes to excel at IB Physics because I live and breathe the subject every day. Whether you need help mastering HL topics, preparing for exams, or crafting an outstanding Internal Assessment, I bring the expertise of a working physicist to every lesson.
