Created by Lang Moore and David Smith of the Connected Curriculum Project, this module investigates the unforced spring equation. This module is part of a larger collection hosted by Duke University.

Created by Lang Moore and David Smith for the Connected Curriculum Project, the purposes of this module are to investigate a mathematical model for spring motion and to study the effect of increased damping. This is one...

The materials presented here use space and spaceflight to introduce students to two areas of the core science curriculum: the motion of the Earth in space, and Newtonian mechanics. Teachers may use these lesson plans and...

This online text is an exhaustive description of the role of symmetry in the degeneracy of a single-particle bound state system in quantum mechanics. Both non-relativistic and relativistic examples are studied.
