GACE Physics

The Physics assessment, offered as part of the Georgia Assessments for the Certification of Educators, is divided into two tests.

The first test consists of 60 selected-response questions. The content areas covered by the first test are mechanics; atomic and modern physics; and thermodynamics. Some of the topics covered by the mechanics subarea are: motion in terms of displacement, velocity, and acceleration; frames of reference and their applications; friction, including forces and coefficients; Kepler’s three laws of planetary motion; and the difference between elastic and inelastic collisions. Some of the topics covered by the thermodynamics, atomic and modern physics subarea are: temperature, temperature scales, heat, and heat capacity; the mechanisms of heat transfer; the organization, structure, and states of matter; and the characteristics, processes, and effects of radioactivity.

The second test consists of 60 selected-response questions. The content areas covered by the second test are electricity and magnetism; optics and waves; and scientific inquiry, processes, technology, and society. Some of the topics covered by the electricity and magnetism subarea are: electric field and electric potential; Coulomb’s law; basic applications of Gauss’s law; simple series, parallel, and combination circuits; and magnetic forces. Some of the topics covered by the optics and waves subarea are: the types of waves and their characteristics; the fundamentals of the Doppler effect; geometric optics; and the characteristics of sound. Some of the topics covered by the scientific inquiry, processes, technology, and society subarea are: experimental design; the nature of scientific knowledge; the impact of physics and technology on society and the environment; how to collect, evaluate, manipulate, interpret, and report data; and safety procedures and precautions for the high school physics laboratory.

The examination must be completed within four hours. Test-takers will receive performance indices indicating their success in each subarea of the examination. Scores will be available approximately a month after the date of the examination; unofficial results are posted on the internet, and an official score report is mailed to the test-taker, the Professional Standards Commission, and the institution specified by the test-taker during registration.
