H2 Physics support that helps you work it out
MOE/SEAB A-Level H2 Physics (9749): Newtonian mechanics, circular motion and gravitation, oscillations and wave superposition, thermal physics, electric and magnetic fields, electromagnetic induction, AC circuits, quantum physics and nuclear physics.
8 tracked MOE/SEAB skills, from uncertainties, 2d projectile kinematics, impulse and collisions to photoelectric effect, wave-particle duality, x-ray spectra and nuclear binding energy. The tutor asks focused questions, you test the next step, and the understanding stays yours.
Beta subject: H2 Physics uses a domain-specific Socratic rubric and is currently marked Beta while we benchmark its scaffolding across full JC 1–2 (A-Level 9749) papers.
What a h2 physics tutor covers
Each skill is tracked separately so strong chapters never mask a shaky prerequisite.
- 1
Uncertainties, 2D projectile kinematics, impulse and collisions
Foundation skillPropagate fractional uncertainties, resolve 2D projectile motion, and apply conservation of linear momentum to elastic and inelastic collisions.
- 2
Forces in equilibrium, upthrust, potential energy gradients and power
Builds on Uncertainties, 2D projectile kinematics, impulse and collisionsSolve static equilibrium with closed vector triangles and torques, and relate F = −dU/dx to potential energy curves.
- 3
Uniform circular motion, gravitational fields, orbits and escape speed
Builds on Forces in equilibrium, upthrust, potential energy gradients and powerConnect centripetal force to banked tracks and vertical loops, and relate gravitational field strength g, potential φ and geostationary orbits.
- 4
Simple harmonic motion (SHM), damping, diffraction and two-source interference
Foundation skillAnalyse x–t, v–t and energy graphs in SHM, and solve Young’s double-slit, single-slit diffraction, diffraction grating and standing wave problems.
- 5
Ideal gas equation, kinetic theory of gases and First Law of Thermodynamics
Foundation skillRelate mean translational kinetic energy to thermodynamic temperature and apply ΔU = Q + W across cyclic p–V processes.
- 6
Electric fields, Coulomb’s Law, equipotentials and potentiometer circuits
Builds on Forces in equilibrium, upthrust, potential energy gradients and powerCalculate E-field and potential V of point charges and parallel plates, and determine balance lengths in potential divider and potentiometer circuits.
- 7
Magnetic fields, Lorentz force, Faraday/Lenz induction and AC transformers
Builds on Electric fields, Coulomb’s Law, equipotentials and potentiometer circuitsTrace charged particles in crossed E and B fields, apply Faraday’s and Lenz’s laws to flux linkage, and compute r.m.s. power in AC circuits.
- 8
Photoelectric effect, wave-particle duality, X-ray spectra and nuclear binding energy
Foundation skillApply Einstein’s photoelectric equation, de Broglie wavelength and Heisenberg uncertainty, and calculate mass defect, binding energy and radioactive decay rates.
How a h2 physics session unfolds
The student starts by asking for the answer—and ends up solving the key step themselves.
- Student
A satellite is moved to a circular orbit of twice the radius. Does its kinetic energy increase or decrease?
- Tutor
Let’s derive the orbital speed relation rather than guessing. Which force provides the centripetal force for a satellite of mass m orbiting Earth of mass M at radius r?
- Student
Gravitational attraction: GMm / r² = mv² / r.
- Tutor
Right. Rearrange that equation to express the kinetic energy Ek = ½mv² directly in terms of G, M, m and r.
- Student
mv² = GMm / r, so Ek = GMm / (2r). When r doubles, Ek is halved — so kinetic energy decreases!
- Tutor
You proved it in two lines. Now combine Ek = GMm / (2r) with gravitational potential energy Ep = −GMm / r to see what happens to the total mechanical energy when r doubles.
About this illustrative example

How skill progress is recorded
Sessions build a clear skill record for the student and a calm, read-only summary for linked parents.
One bar per skill
Mastery is tracked skill by skill, not as a single subject percentage, so a strong topic cannot hide a weak one.
The hint level counts
Getting something right with one small hint moves the bar more than getting it right after five. The number we show you reflects how much help you needed.
Built from an event log
Every attempt, hint and explanation is recorded as an event, and the bars are calculated from that history. It can be replayed, which means the numbers are reproducible rather than asserted.
A parent sees the same numbers
A linked parent gets the same skill bars, the last judgement and its line of evidence behind each level, the recent session summaries and the flag counts — read-only, and nothing that is not also on your own pages.
8 skill bars, tracked independently
In h2 physics, that means 8 separate skill bars — uncertainties, 2d projectile kinematics, impulse and collisions, forces in equilibrium, upthrust, potential energy gradients and power, uniform circular motion, gravitational fields, orbits and escape speed, and the rest — each updating based on verified problem steps. Linked parents see the same topic bars and session takeaways in read-only mode.
H2 Physics FAQs
Common questions from students and parents about studying this subject on tutor.ai.
Which A-Level H2 Physics (9749) topics are tracked?
Aligned to Singapore A-Level H2 Physics (9749). Eight skills, in syllabus order: Uncertainties, 2D projectile kinematics, impulse and collisions; Forces in equilibrium, upthrust, potential energy gradients and power; Uniform circular motion, gravitational fields, orbits and escape speed; Simple harmonic motion (SHM), damping, diffraction and two-source interference; Ideal gas equation, kinetic theory of gases and First Law of Thermodynamics; Electric fields, Coulomb’s Law, equipotentials and potentiometer circuits; Magnetic fields, Lorentz force, Faraday/Lenz induction and AC transformers; and Photoelectric effect, wave-particle duality, X-ray spectra and nuclear binding energy.
How does the tutor handle sign conventions in gravitation, thermodynamics and Lenz’s law?
It asks you to justify why gravitational potential is negative, whether work is done on or by the gas in ΔU = Q + W, and which magnetic pole opposes the flux change before touching the numbers.
Can I use the whiteboard for phasors, field lines and potentiometer circuits?
Yes — sketch your circuit or force diagram on the board and the tutor will read it directly to question your loop or equilibrium equations.
Will it solve multi-step calculation questions for me?
Never. It isolates the governing conservation law or field relationship first and waits for you to carry out the algebra and unit checks.
