IB Physics SL case studies
IB Physics SL · Put your knowledge to work in context.
IB Physics SL is the standard-level physics course within the International Baccalaureate Diploma Programme, a two-year pre-university qualification recognised by universities worldwide. It suits students who want a rigorous, concept-driven physics foundation without the extra depth of Higher Level, and it pairs naturally with mathematics, chemistry, or design subjects. The syllabus moves from measurement and uncertainty through mechanics, thermal physics, waves, electricity and magnetism, circular motion and gravitation, atomic and nuclear physics, and energy production. Practical skills are assessed separately through an internally marked investigation, so data handling and experimental design matter as much as recall. The IB Physics SL case studies are 5 cases and about 2,923 words.
1Pendulum Timing and the Uncertainty Budget
A student uses a simple pendulum to determine g. The length from the pivot to the centre of the bob is measured with a metre rule as 0.842 m, with an estimated reading uncertainty of ±0.002 m.
578 words, about 3 min2Light Gates on a Low-Friction Ramp
A trolley is released from rest and rolls down a ramp inclined at 2.0° to the horizontal, measured with a digital inclinometer reading to ±0.1°. A card of width 2.00 cm is mounted on the trolley.
582 words, about 3 min3Specific Heat Capacity and an Over-Confident Conclusion
A student measures the specific heat capacity of water using an immersion heater. The water has mass 0.500 kg, measured on a balance reading to ±1 g.
637 words, about 3 min4Resonance Tube and the End Correction
A student uses a resonance tube to measure the speed of sound in air. A tuning fork of frequency 512 Hz is held above the open end of a tube whose water level can be adjusted.
489 words, about 2 min5Internal Resistance with the Voltmeter in the Wrong Place
A student determines the emf and internal resistance of a cell. The circuit contains the cell, an ammeter, and a variable resistor in series.
