Course overview — IB Physics
This course develops a coherent, rigorous understanding of the fundamental concepts and principles of physics, emphasizing inquiry, problem-solving and real-world application. It prepares students for the IB Diploma Programme examinations and for further study in physics, engineering and related fields.
Core topics
Measurements and uncertainties: SI units, dimensional analysis, significant figures, uncertainty propagation, precision vs. accuracy.
Mechanics: kinematics, Newton’s laws, work, energy, power, momentum, circular motion, simple harmonic motion.
Thermal physics: temperature, heat, specific heat capacity, heat transfer, kinetic theory of gases.
Waves: wave properties, superposition, standing waves, sound, Doppler effect.
Electricity and magnetism: electric fields and potentials, circuits (DC and basic AC concepts), magnetic fields, electromagnetic induction.
Fields and relativity: gravitational and electric fields, gravitational potential energy, introduction to special relativity (time dilation, length contraction, mass–energy equivalence).
Atomic, nuclear and particle physics: atomic models, nuclear decay, binding energy, radioactivity, basic particle physics and interactions.
Quantum and nuclear physics (higher-level depth where applicable): photoelectric effect, energy quantization, wave–particle duality, nuclear models.
Practical work and experimental skills
Extensive hands-on and virtual laboratories to develop experimental design, data collection and analysis skills.
Emphasis on formulating hypotheses, controlling variables, error analysis and statistical treatment of data.
Internal assessment: individual investigative project where students design and carry out an experiment, analyze results and reflect on limitations and improvements.
Mathematical skills
Use of algebra, trigonometry, vectors, calculus (HL) for modelling and solving physics problems.
Graphical analysis: plotting data, determining gradients and areas, interpreting uncertainties.
Skills developed
Scientific reasoning and critical thinking.
Problem-solving in quantitative and conceptual contexts.
Communication of scientific ideas through written reports, presentations and practical write-ups.
Application of physics to technology, society and the environment; ethical considerations in scientific work.
Assessment
Internal assessment: investigative project assessed by the teacher.
External assessment: written examinations testing core and (for higher level) additional topics, data analysis, and experimental design questions.
Course pathways and preparation
Suitable for students intending to study physics, engineering, maths, or other sciences at university, and for those seeking a strong foundation in scientific literacy.
Recommended prior knowledge: solid foundation in mathematics and basic physical science concepts….
