Purpose

The Energy and Momentum Conceptual Survey assesses students understanding of energy and momentum topics. The energy concepts included the work-energy theorem, conservation of mechanical energy, and work done by gravitational and frictional forces. The momentum concepts included the definition of momentum, impulse-momentum theorem, and conservation of momentum with examples from elastic and inelastic collisions.

Population

The EMCS is designed for introductory algebra-based and calculus-based physics courses.

Typical Performance

We haven't performed an analysis of the LASSO data for typical performance, Singh and Rosengrant (2003) found an average posttest score in calculus-based courses of 49%.

Validity

Singh and Rosengrant published the EMCS in 2003. They found that the instrument was reasonably reliable and valid across introductory physics classes. Relevant articles are listed below:

• Singh, C., & Rosengrant, D. (2003). Multiple-choice test of energy and momentum concepts. American Journal of Physics, 71(6), 607-617.

Research

There are over 130 publications that mention the LSCI. We recommend using Google Scholar and the citations listed under validation to find articles of interest.
