What are ICSE Class 9 Physics half-yearly tests?
ICSE Class 9 Physics half-yearly tests are school-level mid-year examinations based on the CISCE Class 9 Physics syllabus portion completed in the first term. This page gives the ICSE Class 9 Physics Half-Yearly Tests Free PDF links available on ICSE Board and explains how to use those Physics papers for revision, formula practice and numerical answer-writing.
Half-yearly papers are not the same as the final ICSE board paper. CISCE prescribes the syllabus, while individual schools decide how much of the syllabus has been taught by the half-yearly stage and set the test accordingly. Use the PDFs below as practice papers, not as a guarantee that every school will ask the same chapters in the same order.
Concept snapshot: Treat a half-yearly Physics paper like a diagnostic test. It does not finish your preparation by itself, but it shows whether your weak point is formula recall, unit conversion, diagram work, concept explanation or speed.

Before solving any PDF, check which chapters your school has completed. If your school has not yet taught a topic appearing in an older paper, mark that question for later instead of treating it as a current test requirement.
What do these Physics papers test?
The 2019 Physics half-yearly paper available on this page uses an 80-mark structure with Section A and Section B. In that paper, Section A carries 40 marks and is compulsory, while Section B carries 40 marks with a choice of questions. This is useful for practice, but your school may adjust the exact selection depending on its term plan.
The supplied Physics paper material mainly tests three skills:
- Recall with units: naming physical quantities measured in units such as pascal, coulomb, calorie, kelvin and \text{V A}^{-1}.
- Concept explanation: explaining upthrust, floatation, current flow, resistance, temperature change, solar radiation and magnetic effects.
- Numerical application: using formulae such as I=\frac{q}{t}, V=IR, W=qV, density and relative density relations.
The Selina Concise Physics material supplied for this page also includes Magnetism. For ICSE Class 9 Physics revision, students should be able to explain natural and artificial magnets, induced magnetism, magnetic field lines, and why no two magnetic field lines intersect.
| Revision area | What to practise | What the teacher checks |
|---|---|---|
| Measurements and instruments | Least count, pitch, SI units, unit conversion | Correct formula, substitution and unit |
| Fluids and floatation | Upthrust, density, relative density, floating body conditions | Use of displaced liquid idea and correct comparison |
| Heat and energy | Temperature scales, anomalous expansion of water, heat flow | Clear cause-and-effect explanation |
| Current electricity | Charge, current, resistance, potential difference, circuit symbols | Formula plus SI unit in the final answer |
| Magnetism | Induced magnetism, poles, attraction and repulsion, field lines | Correct direction and precise definitions |
Formula map for ICSE Class 9 Physics revision
Keep a formula sheet, but do not memorise symbols without meanings. In Physics, marks are often lost when the formula is correct but the unit or physical quantity is wrong.
| Idea | Formula | Meaning | Unit check |
|---|---|---|---|
| Current | I=\frac{q}{t} | Current equals charge per unit time | \text{A}=\frac{\text{C}}{\text{s}} |
| Charge from current | q=It | Charge equals current multiplied by time | Answer in coulomb, \text{C} |
| Ohm’s law | V=IR | Potential difference equals current multiplied by resistance | \Omega=\frac{\text{V}}{\text{A}} |
| Resistance | R=\frac{V}{I} | Resistance is the ratio of potential difference to current | Answer in ohm, \Omega |
| Work in moving charge | W=qV | Work equals charge multiplied by potential difference | Answer in joule, \text{J} |
| Wave speed | v=f\lambda | Speed equals frequency multiplied by wavelength | \text{m s}^{-1} |
| Floating body | \frac{\rho_{\text{body}}}{\rho_{\text{liquid}}}=\frac{V_{\text{submerged}}}{V_{\text{body}}} | Valid when the body floats in equilibrium | Densities must be in the same unit |
Worked examples from half-yearly-style questions
The examples below are original model solutions based on question types appearing in the supplied ICSE Class 9 Physics half-yearly material. Use the layout as a writing model: formula first, substitution next, unit at the end.
Worked Example 1: Screw gauge pitch and least count
A screw gauge has 50 divisions on its circular scale. Its spindle moves 2\ \text{mm} on the sleeve scale in 4 complete revolutions. Find the pitch and least count.
Step 1: Pitch is the distance moved by the spindle in one complete revolution.
\text{Pitch}=\frac{\text{distance moved}}{\text{number of revolutions}}=\frac{2\ \text{mm}}{4}=0.5\ \text{mm}
Step 2: Least count is pitch divided by the number of circular scale divisions.
\text{Least count}=\frac{0.5\ \text{mm}}{50}=0.01\ \text{mm}
Step 3: Convert the least count to centimetre if required.
0.01\ \text{mm}=0.001\ \text{cm}
Final answer: Pitch =0.5\ \text{mm}; least count =0.01\ \text{mm}=0.001\ \text{cm}.
Worked Example 2: Current drawn by a bulb
A 12\ \text{V} cell is connected to a bulb. The resistance of the bulb filament when it glows is 24\ \Omega. Find the current drawn from the cell.
Step 1: Use Ohm’s law in the form I=\frac{V}{R}.
Step 2: Substitute V=12\ \text{V} and R=24\ \Omega.
I=\frac{12}{24}\ \text{A}=0.5\ \text{A}
Final answer: The current drawn by the bulb is 0.5\ \text{A}.
Worked Example 3: Charge and number of electrons
A conductor carries a current of 0.2\ \text{A}. Find the charge passing through its cross-section in 30\ \text{s}. Also find the number of electrons flowing in this time, taking the charge on one electron as 1.6\times10^{-19}\ \text{C}.
Step 1: Use q=It to find the total charge.
q=0.2\times30=6\ \text{C}
Step 2: Number of electrons is total charge divided by charge on one electron.
n=\frac{q}{e}=\frac{6}{1.6\times10^{-19}}=3.75\times10^{19}
Final answer: Charge =6\ \text{C}; number of electrons =3.75\times10^{19}.
Worked Example 4: Density from floatation
A wooden block floats in water with \frac{2}{3} of its volume submerged. When the same block is placed in oil, \frac{3}{4} of its volume is immersed. Find the density of wood and the density of oil. Take density of water as 1\ \text{g cm}^{-3}.
Step 1: For a floating body, the fraction submerged equals \frac{\rho_{\text{body}}}{\rho_{\text{liquid}}}.
Step 2: In water, \frac{V_{\text{submerged}}}{V_{\text{body}}}=\frac{2}{3}.
\rho_{\text{wood}}=\frac{2}{3}\times1=\frac{2}{3}\ \text{g cm}^{-3}=0.667\ \text{g cm}^{-3}\ \text{approximately}
Step 3: In oil, \frac{3}{4}=\frac{\rho_{\text{wood}}}{\rho_{\text{oil}}}.
\rho_{\text{oil}}=\frac{\rho_{\text{wood}}}{3/4}=\frac{2/3}{3/4}=\frac{2}{3}\times\frac{4}{3}=\frac{8}{9}\ \text{g cm}^{-3}
\rho_{\text{oil}}=0.889\ \text{g cm}^{-3}\ \text{approximately}
Final answer: Density of wood =0.667\ \text{g cm}^{-3} approximately; density of oil =0.889\ \text{g cm}^{-3} approximately.
Examiner’s mindset for Physics answers
In ICSE Class 9 Physics, a numerical answer is not judged only by the final value. A teacher generally looks for the correct relation, correct substitution, correct arithmetic and correct unit. For example, in a current electricity problem, writing I=\frac{V}{R} earns method credit; substituting \frac{12}{24} shows application; ending with 0.5\ \text{A} completes the answer.
For theory questions, use the exact Physics idea. In magnetism, do not write only that iron is attracted. A better answer says that the iron first acquires induced magnetism; the nearer end becomes of opposite polarity; unlike poles attract.
Common mistakes in Physics half-yearly tests
- Leaving the unit out: R=2000 is incomplete; write R=2000\ \Omega or 2\ \text{k}\Omega, as required.
- Using inconsistent units: If volume is in \text{cm}^3 and mass is in \text{g}, the density comes in \text{g cm}^{-3}. Do not write \text{kg m}^{-3} unless you convert.
- Confusing density and relative density: Density has a unit; relative density is a ratio and has no unit.
- Writing a formula without naming symbols: When an answer is theory-based, mention what each symbol represents if the question asks for a definition.
- Forgetting the direction in magnetism: Magnetic field lines outside a bar magnet are taken from the north pole to the south pole. They do not intersect.
- Using a floating body formula in the wrong case: The floating body relation works when the body floats in equilibrium; it is not the same as a body fully held under a liquid by force.
How to use these PDFs for revision
Do not start by reading the paper and checking answers mentally. Physics improves when you write the steps under time pressure.
- First attempt: Solve one PDF in exam style. Keep the paper, rough work and formula sheet separate.
- Mark by error type: Use four columns: concept error, formula error, calculation error and unit error.
- Redo numerical questions: Rewrite every wrong numerical solution using the format shown above.
- Revise weak chapters: If fluids questions are weak, revise density, upthrust and floatation before attempting the next PDF.
- Compare with the syllabus: Use the ICSE Class 9 syllabus page to check whether a topic belongs to your current course plan.
A practical schedule is to solve one paper, revise the two weakest topics, and then solve a second paper after a gap. This gives better feedback than solving all PDFs on the same day.

Frequently Asked Questions
Are ICSE Class 9 Physics half-yearly tests official board papers?
No. ICSE Class 9 Physics half-yearly tests are usually school-level papers based on the CISCE syllabus portion taught in the first term. The PDFs on this page are useful for practice, but your school may set a different selection of chapters and questions.
Which chapters should I revise first for ICSE Class 9 Physics Half-Yearly Tests Free PDF practice?
Start with the chapters that appear repeatedly in the available Physics papers and in your school’s completed syllabus: measurements, fluids, heat, current electricity and magnetism. Then revise any chapter your teacher has marked for the half-yearly test.
How should I write numerical answers in ICSE Class 9 Physics?
Write the formula, substitute the given values, simplify the calculation and end with the unit. For example, in Ohm’s law, write I=\frac{V}{R}, then substitute the values, and finish with current in ampere, \text{A}.
Can I use old Physics half-yearly PDFs for current Class 9 preparation?
Yes, old Physics PDFs are useful for question practice, formula revision and time management. Use them with the current CISCE syllabus and your school notebook, because the term-wise portion can vary from school to school.
What is the best way to revise Physics formulas before the half-yearly test?
Revise each formula with one solved example. For instance, do not only memorise q=It; solve a question where current and time are given, then check whether your final charge is in coulomb.
