Exam-style practice (harder): Physics multiple choice
14 harder, exam-style HSC Physics multiple-choice questions across Modules 5 to 8: projectiles, orbits, fields, transmission, photoelectric data, relativity, decay and spectra. Each is tagged with its question type and every distractor's error is explained. Original practice questions, not from any NESA paper.

Why this set is harder than our topic quizzes
Our topic quizzes check that you know the laws and definitions. The HSC Physics multiple-choice section asks you to use them: a calculation with two or three steps, a data table to extrapolate, or a familiar principle in an unfamiliar setting. Every wrong option is the answer a student gets from one predictable slip.
These 14 questions follow that design. They are original practice questions written by ExamExplained, not questions from any NESA paper. Each explanation starts with a Type tag and names the slip behind every wrong option.
Before looking at the options, write the relationship you are using (for example or ) and do the calculation. Then find your answer among the options. Reading the options first invites you to reverse-engineer a distractor.
The question types
| Type | What it looks like | Typical trap |
|---|---|---|
| Calculation | Projectiles, orbits, relativity, decay series, spectra | Wrong component, missing square or root, powers of ten, applying a factor the wrong way |
| Data interpretation | Tables of planetary data, photoelectric results, activity readings | Reading the table's time step as the half-life; treating an intercept as a gradient |
| Concept application | Forces in circular motion, charged particles in fields | "Centrifugal force", constant speed treated as equilibrium, the right-hand rule for the wrong charge |
| Experimental design | Using a graph to find a constant, measuring across many fringes | Taking the gradient as the answer without asking what it represents |

Four habits that beat the distractors
- Ask "which component?" In projectile questions, vertical quantities use only when the angle is measured from the horizontal.
- Check proportionality before you calculate. Write how the answer scales (, , loss ) and apply the factor.
- Say which frame measures what. The proper time belongs to the frame where the clock is at rest; every other observer measures a longer time.
- Read tables for the pattern, not the step size. A reading every 2 hours does not make the half-life 2 hours.
Using P = V²/R with the transmission voltage to find power lost in the lines. The voltage across the lines is only the drop IR. Work out the current first, then use I²R.
What to do next
- Practise the written half with Mark it yourself: HSC Physics, which shows how NESA marking guidelines award marks for calculations and extended responses.
- Revise Modules 5 and 6 in the mechanics and electromagnetism guide and Modules 7 and 8 in the light and quantum guide.
- Then sit a full NESA past paper under exam conditions.
