Armenia Physics Unified Exam study guide
Armenia Physics Unified Exam · Work through your exam, one topic at a time.
The Armenian Physics Unified Exam (Ֆիզիկայի միասնական քննություն) is the standardized physics examination used within Armenia's unified entrance assessment system for admission to university programs in physics, engineering, and related technical fields. It is intended for secondary-school graduates and other candidates who need a physics result for higher-education admission. The Armenia Physics Unified Exam study guide has 6 sections and about 1,668 words.
01Mechanics: Kinematics, Dynamics, Statics, Conservation Laws
Kinematics describes motion without asking why: distinguish displacement from distance, velocity from speed, and average from instantaneous values. For constant acceleration use the standard relations (v = v₀ + at, s = v₀t + at²/2, v² = v₀² + 2as).
300 words, about 2 min02Molecular Physics and Thermodynamics
The kinetic-molecular model links macroscopic quantities to molecular motion: pressure arises from molecular collisions, and absolute temperature is proportional to average translational kinetic energy, (3/2)kT per molecule. The ideal gas law, pV = nRT (or pV = NkT), connects state variables.
314 words, about 2 min03Electricity and Magnetism
Electrostatics: Coulomb's law gives force between point charges, F = kq₁q₂/r². Electric field E = F/q; field lines point from positive to negative.
278 words, about 1 min04Oscillations, Waves, and Optics
Simple harmonic motion (SHM) occurs when restoring force is proportional to displacement: F = −kx. Then a = −ω²x, with ω = 2π/T.
259 words, about 1 min05Quantum and Atomic Physics
The photoelectric effect: light arrives in photons of energy E = hf. Emission occurs only above a threshold frequency f₀, with maximum kinetic energy K max = hf − W, where W is the work function.
265 words, about 1 min06Methods of Scientific Inquiry and Experimental Data Analysis
Experimental physics requires careful measurement, uncertainty analysis, and clear presentation. Distinguish systematic errors (consistent bias, e.g., a zero error in an instrument) from random errors (scatter that averages out with repeated trials).
