Your uni course won't cover everything on the GAMSAT for physics realise. I'm considering doing the Fundamentals physics subject at UoM which has a few of the same topics, but otherwise I'll have to study things on my own. Look up your course outline and see, and then also ensure to study the missing GAMSAT topics.
Looking around pagingdr, here are two lists people have made:
* Projectile motion and max horizontal range of shot-putter (2005)
* Impulse – area under Force x Time graph (every year)
* F=ma and forces as a runner pushes off from starting block (recent)
* Open and closed pipe – and production of overtones by humming and whistling (recent)
* Archimedes' Principles (every paper)
* Radioactive Decay – Alpha, Beta, Gamma particles (every paper)
and
Vectors (motion, velocity, acceleration)
Mechanics (Newtons laws, friction)
Energy (equations, momentum etc etc)
Elasticity
Electricity and Circuits (calculating resistance etc)
Electric and Magnetic fields
Waves (SHM, interference, photoelectrics effect, EM spectrum)
Radioactive decay (also in chemistry, half life, rate, stability)
Particles vs Waves (particularly with light)
