Content Domains Approximate Percentage of Examination General Science Knowledge 6% Scientific Investigation 7% Classical Mechanics 24% Fluids and Thermodynamics 12% Electricity and Magnetism 24% Waves and Optics 15% Modern Physics 12% About This Exam The American Board for Certification of Teacher Excellence believes that highly skilled physics teachers should possess a comprehensive body of scientific knowledge that is research-based and promotes student achievement. The physics exam is a rigorous assessment of a candidate’s knowledge and application of general physics. The topics assessed are characteristically covered in introductory college level physics courses, although some more advanced questions are included, as teachers must hold a more sophisticated understanding of physics content than that presented to their students. - Page 1 - Physics Exam Snapshot General Science Knowledge • General science knowledge in the subjects of biology, chemistry, and Earth science Classical Mechanics (...continued) Rotational Motion Scientific Investigation • Relationships among kinematic angular quantities • Relationships between kinematic and dynamic angular quantities • Moments of inertia and the parallel axis theorem for extended bodies • Scientific method • Accuracy, precision, and error • Scientific notation and significant digits • Conservation of energy • Procedures for the safe handling of laboratory materials • Conservation of angular momentum Universal Gravitation Classical Mechanics Kinematics and Dynamics • Cavendish experiment • Newton’s universal law of gravity • Kepler’s laws • Gravitational potential energy, force, field strength, and energy conservation • The kinematic quantities position, displacement, speed, velocity, and acceleration • Free-body diagrams • Newton’s first, second, and third laws Fluids and Thermodynamics • Inertial and non-inertial reference frames Mechanics and Fluids • Uniform circular motion • Density and pressure of a fluid • Simple harmonic motion • Pascal’s principle • Archimedes’ principle Work, Energy, Power, and Momentum • Work done by a constant or variable force • Fluid flow rates and fluid flux • Ideal and actual mechanical advantage of simple machines • Bernoulli’s principle and the continuity equation • Conservative and non-conservative forces • Work-energy theorem • Characteristics of the states of matter • The relationship between energy and power • Ideal gas law • Impulse-momentum theorem • Kinetic theory of gases • Conservation of linear momentum • Equipartition theorem • Pressure versus temperature phase diagrams • Mechanisms of heat flow Thermodynamics - Page 2 - Physics Exam Snapshot Fluids and Thermodynamics (...continued) • Calorimetry • 0th, 1st, 2nd, and 3rd laws of thermodynamics • Thermodynamic cycles of gases Magnetism (...continued) Electricity and Magnetics • Magnetic force on a current-carrying wire in a uniform magnetic field • Biot-Savart law • Torque on a current-carrying loop in a uniform magnetic field • Diamagnetism, paramagnetism, and ferromagnetism Electrostatics • Insulators and conductors • Coulomb’s law • Electric field and its relation to force and charge • Ampère’s law, Faraday’s law, and Maxwell’s equations • Ampère’s law • Faraday’s law Electric flux and Gauss’ law • Self-inductance and mutual-inductance • Electrostatic potential • • Electric dipoles AC circuits containing series and parallel combinations of capacitors, inductors, and resistors • Capacitance • Maxwell’s equations • Energy density, energy flux, and radiation pressure for electromagnetic waves Electric Currents • Relationship between electric charge and electric current • Microscopic model for charge flow in a material • Ohm’s law • Energy and power relations in an electrical circuit • Waves and Optics Waves Resistance of series and parallel networks of resistors • Kirchhoff’s rules • Charging and discharging capacitors in timedependent RC circuits Magnetism • Magnetic field lines for a bar magnet • Magnetic force on a charged particle moving in a magnetic field - Page 3 - • Mechanical waves • Electromagnetic waves and the electromagnetic spectrum • Amplitude, wavelength, period, frequency, angular frequency, speed, wave number, phase, and polarization • Superposition and interference of waves • The Doppler effect Physics Exam Snapshot Waves and Optics (...continued) Modern Physics (...continued) Geometric (Ray) Optics • Photoelectric effect • Law of reflection • Bohr's model for a hydrogen atom • Refraction and reflection of light • α, β, and γ decay for radioactive nuclei • Total internal reflection • Thermonuclear fusion reactions • Dispersion of light • Polarization for light • Nature of polarization for light • Convex and concave mirrors Physical (Wave) Optics • Huygens’ principle • Multi-slit interference • Diffraction of light • Interference phenomena involving a thin film • Michelson interferometer Modern Physics • Michelson-Morley experiment • Thomson’s measurement of the charge-tomass ratio of the electron • M.
