Pearson Edexcel International GCSE Physics (4PH1)
Physics revision
9 topics across two units. Pick any one to be tested on it, taught it, or to talk it through. This is the course list Zen IQ works from: its tutor, papers and marking all follow it.
Unit 1 4WPH1
- Forces and motionSpeed/velocity/acceleration graphs; F=ma; weight=mg; Hooke's law; momentum; moments
- ElectricityMains safety (fuses, earthing); P=IV; series/parallel circuits; I-V graphs (LDR, thermistor, diode); V=IR; Q=It; electrostatics
- Energy resources and transferEnergy stores and transfers; efficiency; Sankey diagrams; conduction/convection/radiation; work done W=Fd; KE=1/2mv2; GPE=mgh; power; electricity generation methods
- Solids, liquids and gases Part 1Density; pressure; change of state and specific heat capacity
Unit 2 4WPH2
- WavesTransverse vs longitudinal; wave speed=freq×wavelength; EM spectrum and uses/dangers; reflection/refraction; refractive index; critical angle and total internal reflection; sound waves
- Solids, liquids and gases Part 2Ideal gas laws (pressure-volume, pressure-temperature relationships)
- Magnetism and electromagnetismMagnetic fields; electromagnets; motor effect; transformers (turns ratio)
- Radioactivity and particlesAtomic structure; alpha/beta/gamma; nuclear equations; half-life; fission and fusion
- AstrophysicsOrbital motion; stellar evolution (nebula→main sequence→red giant→white dwarf); Big Bang evidence, red-shift
How Zen IQ helps with Physics
Papers written in the Edexcel style for Physics, with a mark scheme, marked part by part, crediting an error carried forward the way a real examiner does.
Every topic below turns strong, shaky or weak from your marks and flashcards, so you can see where marks are going. A target test aims straight at the weakest.
Talk a topic through out loud with Zehan or Maya. They answer in a second, you can cut in, and they write it on a board as they explain.
Any topic taught in about four minutes as an animated lesson, or drawn as a mind map where every idea leads to a lesson, a quiz or a call.
Cards that come back just before you would forget them, and study guides in three lengths, ready to print or download for Word.
