Physics Zen

CEEC (大考中心)

AST Physics (分科測驗 物理)

Focused practice for the 分科測驗 physics paper across its five elective courses: mechanics, gases, waves and optics, electricity and magnetism, and modern physics. Also covers the physics in the GSAT (學測) science paper. Fluids and capacitors are not included.

49 skills · g = 9.8 m/s²

Conventions

  • The path has 49 skills for the 分科測驗 physics paper: the required physics course, the five advanced elective courses and the junior-high prerequisites.
  • It also covers the content of the physics in the GSAT (學測) science paper, but GSAT physics items are mostly short conceptual questions, often multiple-select, and the path drills numeric problems.
  • Multiple-select items, graded derivations and drawn graphs are not simulated. Pulse superposition, Huygens' principle, how electromagnetic waves are produced and measurement uncertainty are not drilled; fluids, capacitors and the moment of inertia are not on the path.
  • Problems use g = 9.8 m/s².
  • Physics Zen is independent exam-style practice, not official exam material, and is not affiliated with the CEEC (大考中心).

Waves, Light and Sound

Electromagnetism I

  • Charge & Coulomb's Law: Find the force between two charges and count the electrons behind a charge
  • Electric Field: Get the field from a force on a test charge and from a source charge at a distance

  • Photons & Photoelectric Effect: Get a photon's energy from its wavelength and the electrons it can knock loose
  • Matter Waves & X-rays: Find the de Broglie wavelength of a particle, the cutoff of an X-ray tube and the spacing from a Bragg reflection
  • Energy Levels: Find the photon an atomic transition emits, in electronvolts and in nanometres
  • Radioactive Decay: Halve an activity across half-lives and name the nuclide a decay leaves behind
  • Mass-Energy: Convert a mass defect into energy and find the binding energy per nucleon

How Physics Zen helps

The path follows the five elective courses the 分科測驗 physics paper examines, plus the required physics course and the junior-high prerequisites, with g = 9.8 m/s² already set. At the harder levels, twenty original exam-style items are mixed into their skills: most answer with five options, as the paper's single-choice questions do, and some ask for a written numeric answer, from Millikan's oil drop and Thomson's e/m to the Bohr model and thin films. Every skill generates fresh problems with instant checking and a worked solution.
