§ Year 11 · Physics · QCAA Senior
Year 11 Physics.
The year the formulas need to make sense, not just get memorised.
Year 11 Physics IAs do not count toward your ATAR. That is exactly why so many students treat them casually — and exactly why they walk into Year 12 missing the conceptual base the EA assumes. Unit 1 and Unit 2 are not "warm-up" content. They are the rules that Unit 3 and 4 quietly use on every question. We make sure the foundation is solid before the marks start counting.

§ What Year 11 covers
The syllabus, in plain English.
Year 11 Physics covers QCAA Units 1 and 2. Unit 1 (Thermal, nuclear and electrical physics) runs Terms 1 and 2. Unit 2 (Linear motion and waves) runs Terms 3 and 4. The IAs are formative — they do not count toward ATAR — but the topic understanding you build here is exactly what Units 3 and 4 will assume you know cold.
Unit 1: Thermal, nuclear and electrical physics
- Heating processes — kinetic particle model, specific heat capacity, latent heat, conduction, convection, radiation
- Ionising radiation and nuclear reactions — nuclear stability, alpha, beta, gamma decay, half-life, mass-energy equivalence (E = mc²)
- Fission and fusion — energy per nucleon, binding energy
- Electrical circuits — current, voltage, resistance, Ohm's law (V = IR), series and parallel
- Electrical power and energy (P = VI, P = I²R)
Unit 2: Linear motion and waves
- Kinematics in one dimension — displacement, velocity, acceleration, SUVAT equations
- Newton's laws of motion, free-body diagrams, F = ma
- Momentum and impulse, conservation of momentum in collisions
- Mechanical energy — work, kinetic, gravitational potential, conservation of energy
- Wave properties — wavelength, frequency, period, longitudinal vs transverse, reflection, refraction, interference, standing waves
§ Assessment
Three internal assessments through Year 11. None count toward ATAR — but the school uses them to predict and place you. A weak Year 11 IA result usually triggers a Year 12 subject change conversation.
IA1 — Data test
Formative
A 60-minute supervised test on data analysis — graph reading, calculating gradients, error and uncertainty, significant figures. Practice with real datasets, not just plug-in calculations.
IA2 — Student experiment
Formative
A practical investigation written up as a 1500–2000 word scientific report. Often based on a kinematics, electrical, or waves experiment. The rationale and evaluation sections are where most marks are won and lost.
IA3 — End-of-Unit exam
Formative
A 90-minute supervised exam covering Unit 2. Short and extended response. This is the closest format to what the Year 12 EA will eventually ask.
§ Where Year 11s get stuck
Common pitfalls — and how to dodge them.
Confusing weight (N) with mass (kg)
Weight is a force, measured in newtons (W = mg). Mass is the amount of matter, measured in kilograms. A 5 kg object has a weight of approximately 49 N on Earth. Writing "weight = 5 kg" or "mass = 49 N" on a force diagram costs marks immediately, and the confusion carries straight into Unit 3 gravitational fields next year.
Treating velocity as a scalar in 1D problems
Velocity has direction even in one dimension — positive or negative. A ball thrown straight up has initial velocity +20 m/s and acceleration −9.8 m/s². Students who treat both as positive get the wrong final position, the wrong time of flight, and the wrong answer to nearly every SUVAT question. Always define a positive direction first and stick to it.
Using V = IR for the wrong component
In a series circuit with two resistors, V_total = I × R_total, but the voltage across each individual resistor is I × R_individual. Students apply Ohm's law to the whole circuit when the question asks about one resistor, or vice versa. Always identify what V, I and R refer to before plugging in.
Forgetting to use radians where the formula expects them
Wave equations and rotational quantities use radians, not degrees. If your calculator is in degree mode when you compute sin(ωt) for a wave at t = 0.1 s, you will get nonsense. The fix is one button on the calculator, but missing it loses an entire calculation.
Mixing up speed of light and speed of sound
3 × 10⁸ m/s is the speed of light in vacuum. The speed of sound in air is roughly 340 m/s. Using the wrong constant in a wave-speed calculation gives an answer that is off by a factor of about a million — and yet students do this under exam pressure. Write the constant down with its units before substituting.
§ Worked examples
A question. A walkthrough. The marks.
Example 1
A vertical motion SUVAT problem
The question
A ball is thrown vertically upward from ground level with an initial velocity of 25.0 m/s. Taking upward as positive and g = 9.80 m/s² downward, find (a) the maximum height reached, and (b) the time to return to ground level. Ignore air resistance.
Walkthrough
Define: up is positive, so u = +25.0 m/s and a = −9.80 m/s². Part (a) — Maximum height: at the top, v = 0. Use v² = u² + 2as. 0 = (25.0)² + 2(−9.80)s. Solving: 19.6s = 625, so s = 31.9 m. Part (b) — Time to return to ground: displacement back at the start is s = 0. Use s = ut + ½at². 0 = 25.0t + ½(−9.80)t² = 25.0t − 4.90t² = t(25.0 − 4.90t). Solutions: t = 0 (launch) or t = 25.0/4.90 = 5.10 s. Answer: max height 31.9 m, total time 5.10 s. Mark allocation in a 6-mark question: 1 for defining direction, 1 for correct u and a values with signs, 2 for part (a) working and answer, 2 for part (b) working and answer. Students who do not write the sign convention at the top frequently lose marks even when their arithmetic is right because the marker cannot follow the logic.
Example 2
Series-parallel circuit analysis
The question
A 12 V battery is connected to a 4 Ω resistor in series with a parallel combination of a 6 Ω and a 3 Ω resistor. Calculate the total current drawn from the battery and the current through the 6 Ω resistor.
Walkthrough
Step 1 — Parallel combination: 1/R_p = 1/6 + 1/3 = 1/6 + 2/6 = 3/6, so R_p = 2 Ω. Step 2 — Total resistance: R_total = 4 + 2 = 6 Ω. Step 3 — Total current from battery: I = V/R = 12/6 = 2.0 A. Step 4 — Voltage across the parallel section: V_p = I × R_p = 2.0 × 2 = 4.0 V. Step 5 — Current through 6 Ω resistor: I₆ = V_p / 6 = 4.0/6 = 0.667 A. Check: I through 3 Ω = 4.0/3 = 1.33 A; sum = 0.667 + 1.33 = 2.0 A ✓ (matches total current). Common mark loss: applying V = IR with the total voltage (12 V) to find the current through the 6 Ω resistor directly — that ignores the voltage drop across the 4 Ω resistor.
§ Why Pythora for Year 11 Physics
Not generic tutoring. Specifically this.
Tutors who recently sat Year 12 Physics
Every Pythora Physics tutor sat the QCAA Physics external in the last few years. They know which Year 11 topics get glossed over in class and then come back to bite in Year 12 — and they teach Year 11 with the Year 12 endpoint in mind.
Real lab-report scaffolding for IA2
Year 11 student experiment is most students' first proper scientific report. We work through the rationale, methodology, results analysis and evaluation structure with you so the format becomes automatic — by Year 12, you are not learning how to write a scientific report, you are focused on the physics.
Bridging the algebra gap
Physics is half algebra. Most "I cannot do Physics" problems are actually "I cannot rearrange equations" or "I do not handle units carefully" problems. Our tutors diagnose that on day one and fix it alongside the physics content.

§ Real student
“I was about to drop Physics after Term 1. My tutor went back and rebuilt my SUVAT and force-diagram technique from scratch, and by IA3 I was the top of my class. Year 12 actually feels manageable now.”
§ Where this fits
One step on the path.
The jump from Year 10 science into Year 11 Physics is steep — Year 10 covers physics as one strand of general science, Year 11 assumes you can manipulate equations, draw force diagrams, and reason with vectors from day one. The jump from Year 11 to Year 12 (where calculus-style reasoning about fields and electromagnetism enters) is even steeper. We tutor with the Year 12 endpoint in mind from the first session.

Year 12 Physics§ Questions
Frequently asked.
If Year 11 Physics IAs do not count toward ATAR, does it matter how I do?
Yes, more than students realise. Schools use Year 11 results to predict Year 12 performance and to gatekeep subject continuation. A weak Year 11 IA3 often triggers a school conversation about switching subjects. More importantly, every gap in Year 11 understanding becomes a Year 12 EA gap — and that exam is worth 50% of your final grade.
My child got into Year 11 Physics but is struggling with the maths. Should they drop?
Usually no, especially not in Term 1. Most students underestimate how much algebraic manipulation Year 11 Physics requires. Three to five sessions focused on rearranging equations, unit handling, and SUVAT technique typically closes the gap. The students who quit early almost always regret it later when their classmates breeze into engineering at uni.
How does tutoring help with the Year 11 student experiment IA?
We help with the structure and the physics, not the writing itself — that has to be the student's work for academic integrity reasons. Sessions cover: refining the research question, designing a method that actually controls variables, the analysis section (graph types, gradient calculations, uncertainty), and the evaluation. Most marks are won in the evaluation section, which is also where students rush.
