Physics

Use core physics to explain how celestial bodies behave.

Foundations in physics introduces the core language and tools you’ll use throughout GAMSAT physics, from physical quantities and SI units to careful measurement, uncertainty, and error. It also builds the vector and scalar skills needed to interpret diagrams, resolve forces, and model motion and fields confidently.

Apply physics principles directly to healthcare contexts, especially imaging and radiation. Cover X-rays/CT/MRI/ultrasound at a conceptual level, plus dose, attenuation, and effects.

Understand nuclei, isotopes, and radioactive decay, including half-life and decay modes. Link these concepts to medical tracers, PET/SPECT principles, and radiation shielding basics.

Get a high-level view of fundamental particles and forces, without heavy maths. Know what particles are, how energy–mass relates, and why concepts like antimatter and interactions matter in modern physics applications.

Understand temperature, heat, and energy transfer (conduction, convection, radiation) through the lens of the laws of thermodynamics. Practise using specific heat, phase changes, and ideal gas relationships in biological and everyday contexts.
