This complete study guide for WGU C165 Integrated Physical Sciences contains actual exam questions with 100% verified correct answers for the latest 2026 version. It is designed to help you pass the Objective Assessment with an A grade and covers all major topics in an integrated approach to physics, chemistry, and earth science. Key Topics Covered: Scientific Method & Inquiry — Essential attributes of science, principle of falsification, hypothesis vs law vs theory, variables (independent, dependent, control), observational studies, models (physical, conceptual, mathematical, computer). Physics & Motion — Linear momentum (mass × velocity), velocity, acceleration, force, net force, balanced forces, Newton's three laws of motion, inertia, friction (kinetic, static, fluid resistance), gravity, work (force × displacement), energy (kinetic, potential: gravitational/chemical/elastic), law of conservation of energy and momentum, elastic vs inelastic collisions, elasticity. Waves & Sound — Oscillation, wave properties (amplitude, wavelength, period, frequency, crest, trough), mechanical vs electromagnetic waves, transverse vs longitudinal waves, sound waves, compression/expansion. Chemistry & Matter — Matter, atoms, valence electrons, elements, atomic number, compounds, pure substances vs mixtures (heterogeneous/homogeneous), chemical bonds (ionic, covalent, metallic), organic vs inorganic compounds, physical vs chemical changes, law of conservation of matter, coefficients in reactions, temperature vs thermal energy. Earth Science & Atmosphere — Layers of Earth's atmosphere (troposphere, stratosphere with ozone layer, mesosphere, thermosphere, exosphere), weather phenomena (air masses, fronts: warm/cold, high/low pressure systems), rock cycle, rock types (sedimentary, igneous, metamorphic), weathering (physical/chemical), erosion, deposition, minerals, plate tectonics (convergent, divergent, transform boundaries, subduction), Earth's layers (crust, mantle, outer/inner core), geologic time (eons and eras: Precambrian, Paleozoic, Mesozoic, Cenozoic), principles of superposition and crosscutting relationships. Additional Concepts — Convection, transpiration, infiltration, runoff, groundwater, nebulae, nuclear fusion, stars, galaxies, asteroids, comets, moons. Perfect for WGU C165 students seeking a guaranteed A+ on the exam.
