AEPA Physics (NT308) case studies
AEPA Physics (NT308) · Put your knowledge to work in context.
The AEPA Physics (NT308) is one of the Arizona Educator Proficiency Assessments, a subject-knowledge test listed by the AEPA program among its Knowledge Tests. Candidates take it to demonstrate the physics content knowledge Arizona requires for a teaching certificate; because testing requirements depend on certification type, candidates should confirm with the program which tests their own certificate path requires. The AEPA Physics (NT308) case studies are 5 cases and about 2,264 words.
1Cart on a Ramp: Interpreting Discrepant Acceleration Data
A physics class uses a 0.500 kg cart on a low-friction inclined track set to 8.0 degrees. A motion sensor records position vs.
