Physics tuition, Class 9 and 10

Physics isn't separate at Class 9–10 in most Indian schools—it's integrated with Chemistry and Biology in Science, examined together. But it fails separately, so it's worth addressing on its own.

Class 9 covers motion, force and laws of motion, gravitation, work and energy, and sound. Class 10 moves to light—reflection and refraction—the human eye, electricity, and magnetic effects of current.

These two years are structurally different, which explains a common pattern. Class 9 physics is mostly mechanics: one family of ideas, heavily numerical, built on algebra. Class 10 is more varied—light and electricity each have their own conventions and diagrams. A student can manage one year but struggle the other for reasons unrelated to effort.

NCERT has revised Class 9–10 Science multiple times in recent years, and schools use different editions. We teach from your child's actual textbook, not a syllabus list. A photo of the contents page is most useful.

If your child can state Newton's second law correctly but still cannot finish the numerical problem, physics is not the problem. This is the single most common issue we find in Class 9.

The arithmetic in physics quietly depends on:

• Rearranging a formula. Moving from one form to another without dropping a sign. This is Class 7 and 8 algebra, and this is where most numerical marks actually disappear.
• Powers of ten and standard form. Multiplying and dividing quantities written as ten to the power of something without producing an answer a thousand times too large.
• Unit conversion before substitution. Kilometres per hour into metres per second, centimetres into metres, grams into kilograms. Converting after you calculate rather than before is a quiet, repeating, costly error.
• Decimals and ratios. Especially in electricity, where parallel resistances produce fractions students find genuinely unfamiliar.

This matters hugely because the fix depends entirely on the diagnosis. More physics practice does nothing for a student whose algebra is weak - it just creates more wrong answers with better-remembered formulas. A few weeks fixing the maths itself often improves the physics mark more than a whole term of physics revision.

The check takes five minutes. Give your child a formula and ask them to make a different letter the subject, with no physics attached. If that is hard, you have found the problem.

Three areas of Class 9 and 10 physics often escape explicit teaching and rely on osmosis instead.

Derivations. Students typically memorise them as separate blocks of text and reproduce them with steps missing, which loses marks because each step is marked individually. When taught as a chain - where each line follows from the one before for a stated reason - they become reconstructible rather than memorised, and your child can rebuild any forgotten line.

Ray diagrams. These are drawing skills combined with conventions: arrows on rays showing direction, objects drawn as arrows, dotted lines for virtual rays, the principal axis and focus marked. Most diagram marks are lost to conventions never taught, rather than to physics misunderstood.

Circuit diagrams. Standard symbols drawn with a ruler, ammeter in series and voltmeter in parallel. Redrawing a messy circuit cleanly before solving it catches most errors - this redrawing is the technique itself, not simply a neatness habit.

All three need weekly practice rather than revision cramming, because all three are habits.

All classes meet in batches, with every student working through a numerical at the board each session. This shows exactly where the working breaks down, not just whether the answer is wrong.

• Diagnose maths first. Before any physics tutoring, we diagnose algebra, units and powers of ten. If those are causing the problem, we say so and fix them.
• Units written at every line. Not just in the final answer. It catches conversion errors before they compound.
• Estimate before calculating. About how large should this answer be? This catches decimal-point errors that even careful calculations can miss.
• Derivations rebuilt, not recited. We ask students to justify each line, so they can rebuild any forgotten steps.
• Board-pattern questions from Class 9. By the time the actual exam comes, the format should feel familiar.

If a student needs to close a specific gap quickly, one-to-one for a term is usually the most efficient approach before moving to batch classes. Find both options on the fees page, and the assessment is free.
