There are many advantages for faculty and students, including elimination of paperwork, better chances for understanding students’ state of comprehension, a more relaxed environment, and no possibility for gaming for points. The ongoing pandemic has amplified many questions I […]

Vector Formalism in Introductory Physics VI: A Unified Solution for Simple Dot Product and Cross Product Equations

TL;DR: Simple vector dot products and cross products may be “undone” using formal methods consistent with Gibbsian vector algebra. Writing the cross product and dot product of an unknown vector relative to a given vector in a canonical form allows a well known vector identity to be used to isolate the unknown vector. Special cases […]
