Motion under forces, resisted projectile motion, and simple harmonic motion, derived from Newton's second law.
These are the statements the Mathematics Extension 2 syllabus makes about Mechanics. Dux records each one against the questions you answer, so you can see which of them you have actually been tested on and which have never been asked.
Newton's second law as a differential equation, with forces resolved and acceleration written in terms of velocity or displacement.
Projectile motion where a resistive force acts, and the difference this makes to range and trajectory.
The defining differential equation, the relationship between displacement, velocity and acceleration, and the period of motion.
Motion under gravity with a resistance proportional to velocity or its square, and the terminal velocity that follows.
HSC Mathematics Extension 2 - Trial Paper Shape is 100 marks in 180 minutes. Questions on Mechanics are not one shape repeated: the command word decides what the marker is looking for, and the mark value decides how much of it. These are the ones Mathematics Extension 2 uses.
Dux writes practice for this module in exactly these shapes, so the drill is the same task the paper sets — not a general knowledge quiz with the module name on it.
Mechanics is module 6 of 6 in Mathematics Extension 2. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Mathematics Extension 2 dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
