Peer reviewedBarnes, Aaron – American Journal of Physics, 1977
Examines the geometrical interpretation of the vector operation curl for vector fields "A" such that "A" dot curl "A" is not equal to zero. (MLH)
Descriptors: College Science, Higher Education, Instructional Materials, Mathematical Applications
Peer reviewedKonopinski, E. J. – American Journal of Physics, 1978
An explicit physical interpretation of the electromagnetic vector potential is indicated as field momentum available for exchange with kinetic momenta of charged matter. (BB)

Peer reviewedBasano, L.; Bianchi, A. – American Journal of Physics, 1980
Discusses how the Runge-Lenz vector provides a way to derive the relation between deflection angle and impact parameter for Coulomb- and Kepler-fields in a very simple and a straightforward way. (Author/HM)
