Multiple-choice test of energy and momentum concepts
Chandralekha Singh, David Rosengrant
TL;DR
This study assesses introductory physics students' understanding of energy and momentum through a 25-item multiple-choice test and interviews, revealing widespread difficulties in interpreting and applying core principles.
Contribution
It introduces a specialized multiple-choice test and qualitative interviews to evaluate student comprehension of energy and momentum concepts.
Findings
Students struggle with qualitative interpretation of energy and momentum principles.
Most students have difficulty applying concepts in physical situations.
The test reveals common misconceptions and gaps in understanding.
Abstract
We investigate student understanding of energy and momentum concepts at the level of introductory physics by designing and administering a 25-item multiple choice test and conducting individual interviews. We find that most students have difficulty in qualitatively interpreting basic principles related to energy and momentum and in applying them in physical situations.
