Complete Guide to HSC Physics Module 5 – Advanced Mechanics

Welcome to HSC Physics Module 5: Advanced Mechanics.

In this guide, I’ll break down:

• The 5 most essential concepts in the module (with clear examples)
• Key skills you need to succeed in both exam questions and in-depth studies
• Sample MCQ and extended response with working

Key Concept 1: Projectile Motion in Two Dimensions

This is your first step into multi-directional motion. While Year 11 focused on linear motion (acceleration, velocity, displacement in 1D), here you’re dealing with two-dimensional motion under the influence of gravity.

You’ll split every projectile’s velocity into:

• Horizontal component → constant (no acceleration)
• Vertical component → accelerates due to gravity (−9.8 m/s²)

Core skills:

• Use trigonometry to resolve velocity vectors: $v_x = v\cos\theta$ and $v_x = v\sin\theta$
• Apply the SUVAT equations separately in each direction
• Calculate time of flight, max height, and horizontal range
