AAPT NCPT (Level 1) study guide
AAPT NCPT (Level 1) · Work through your exam, one topic at a time.
The AAPT NCPT (Level 1) is presented as a national competency physics test at introductory level, associated with the American Association of Physics Teachers. AAPT describes itself as "a professional membership association of scientists dedicated to enhancing the understanding and appreciation of physics through teaching," and its public site emphasizes professional development, contests and competitions, and student enrichment programs. The AAPT NCPT (Level 1) study guide has 6 sections and about 1,664 words.
01Mechanics
Newton's three laws, vector resolution of forces, static and kinetic friction, and the distinction between mass and weight anchor this domain. Be fluent with kinematics equations for constant acceleration, projectile motion (independent horizontal and vertical components), uniform circular motion (centripetal acceleration directed toward the center), work-energy and impulse-momentum theorems, and conservation of momentum in one and two dimensions.
279 words, about 1 min02Thermodynamics and Kinetic Theory
Understand the ideal gas law (PV = nRT), the first law (ΔU = Q − W with work done by the gas), and the distinction between state functions (U, T, P, V) and path-dependent quantities (Q, W). Know the four basic processes: isothermal (ΔT = 0, ΔU = 0 for ideal gas), adiabatic (Q = 0), isobaric (W = PΔV), and isochoric (W = 0).
309 words, about 2 min03Waves and Optics
Know the wave equation v = fλ, superposition, and the conditions for constructive and destructive interference (path difference of mλ and (m + ½)λ). For standing waves on strings and in pipes, identify nodes and antinodes and the harmonic series; open pipes support all harmonics, closed pipes only odd ones.
286 words, about 1 min04Electricity and Magnetism
Master Coulomb's law, electric field and potential (E = kQ/r², V = kQ/r), and the behavior of conductors in electrostatic equilibrium (field inside zero, charge on the surface). Apply Ohm's law, series and parallel resistor rules, and Kirchhoff's laws for multi-loop circuits; know power dissipation P = I²R = V²/R.
279 words, about 1 min05Modern Physics
Understand the photon model (E = hf = hc/λ), the photoelectric effect (threshold frequency, work function, maximum kinetic energy KE max = hf − φ), and the de Broglie wavelength λ = h/p. Know atomic energy levels and that emitted or absorbed photon energy equals the level difference.
265 words, about 1 min06Laboratory and Experimental Skills
Know how to design a controlled experiment: identify independent, dependent, and controlled variables, and choose instruments with appropriate precision. Understand significant figures, unit conversions, and propagation of uncertainty (add absolute uncertainties for sums; add fractional uncertainties for products and quotients).
