Physics simulations

39 interactive models: 20 for O Level and 22 for A Level. Drag and adjust the model directly, work through the "Try this" tasks, then explain the result with the related lesson. A model does not replace experimental evidence or exam working.

All simulations are in beta. Looking for quizzes? Open the practice browser.

O Level Essentials

Common O Level repair points.

  • Forces & Motion ExplorerBuild the force picture first, then decide resultant force, acceleration, and motion change.
  • Light & Lens ExplorerTrace rays for reflection, refraction, TIR, and lenses from one mobile-safe diagram set.
  • Thermal Physics ExplorerCompare transfer methods and heating curves so temperature change and state change link up.
  • I-V Characteristics LabRead resistor, lamp, and diode curves so slope and resistance stop feeling separate.
  • Work, Energy & EfficiencyWatch GPE, KE and thermal energy change as a trolley rolls, and trace useful and wasted energy as a motor lifts a crate.

A Level Core

A Level mechanics, circuits, oscillations and waves.

  • Kinematics Graph ExplorerShape a velocity–time graph and watch the car, the displacement–time and the acceleration–time graphs follow it.
  • Projectile Motion ExplorerSplit launch speed into components, then compare angle, range, flight time, and drag.
  • Potential Divider LabTrack how resistor ratios, sensor placement, and output loading change Vₒᵤₜ and current.
  • SHM ExplorerRelease a mass or a pendulum and read x, v and a at the same instant on linked graphs.
  • Collisions & Momentum LabCollide gliders on an air track and read momentum, kinetic energy and the force–time graph of the impact.

Practical Skills

Instrument reading, uncertainty, graphs and planning.

  • Vernier Caliper TrainerRead the main scale and aligned vernier mark fast, then lock the final cm reading.
  • Micrometer TrainerRead sleeve plus thimble, then fix the reading with the correct zero-error sign.
  • Vernier Zero-Error TrainerRead closed jaws, decide sign, and correct the observed caliper reading without sign slips.
  • Practical Circuitry LabBuild, repair, and measure circuits with correct meters, rheostat use, and sensible practical workflow.
  • Uncertainty & Error LabWork through readings, repeats, propagation, and final reporting with Paper 4-style uncertainty checks.
