14 Physics Core Syllabus • Basics - S.I. system of units, scalars and vectors. • Rectilinear Motion - velocity and acceleration, graphs of motion, equations of motion. • Forces - resultant forces, weight and mass, resolving forces, centres of gravity, upthrust and flotation, moments, Newton’s laws. • Dynamics - projectiles, momentum, circular motion. • Energy - forms of energy, energy transfers, conservation of energy, KE and PE and associated formulae, power. • Gases - The gas laws, ideal gas, absolute temperature scale, meaning of temperature. • Thermal energy - transfer (conduction, convection and radiation), heat capacity, latent heat, thermodynamics. • Electric circuits - current and potential difference, combinations of resistances, resistivity, EMF, internal resistance, capacitors and capacitor equations. • Electric fields - Coulomb’s law, comparison with gravitational fields. • Magnetic fields - electromagnetism (uses and formula), mass spectrometry. • Waves - mechanical waves, wave phenomena, superposition of waves, interference patterns, standing waves. • Optics - refractive index, lenses and lens formulae, focal lengths, real and virtual images, the eye (application of the above topic to the eye and defects of vision). • Simple Harmonic Motion - formulation, resonance, damped oscillations. • Sound - intensity, logarithm dB scale. • Radioactivity - nuclear decay (alpha, beta, gamma), exponential decay, half-life • Nuclear reactions - mass-energy equivalence, fission and fusion. • Medical physics - x-rays, ultrasound, optics in medicine, radio-isotopes, Magnetic Resonance Imaging. Where possible, topics are covered so that the following aspects are stressed: • Analysis and interpretation of graphs. • Mathematical patterns (direct and inverse proportionality, exponential changes, log scales etc). • Quick approaches to solutions. • Conversions of simple (eg: µA to mA) and more complex units (eg: g cm-3 to kg m-3). It is important to note that these cross-curricular techniques will also serve to reinforce your work in the other sciences. PHYSICS Written for what many students consider the most challenging section of the GAMSAT, this guide will prepare you in all of the theory, and skills required for the Physics component of section III. Dealing with both the mathematical and conceptual topic areas regularly tested, this guide will train you in both your quantitative and qualitative understanding of Physics for the examination. Through detailed experience and analysis of the GAMSAT we show you how to approach any question sets, whatever your level of mathematical knowledge. This is constantly reinforced by application to sample GAMSAT problems to develop understanding. GRADMED expert GAMSAT preparation since 2002.
