Conceptual Understanding in Introductory Physics XXVII: Mass and Charge

This question is inspired by my recent ramblings on electric charge and by the elements of thought in the Paul/Elder critical thinking framework. (a) In first semester physics, you learned that mass is necessary to calculate the gravitational force shared by two interacting entities. What are the physical implications of mass always being positive? (b) …

Conceptual Understanding in Introductory Physics III: Interpreting Physical Quantities

This series continues with a question which, I hope, causes readers and students to reflect on something that is frequently omitted from traditional introductory physics courses. I contend that words are all we have to convey conceptual understanding in physics or any other topic. Yet, in science courses, and especially in physics courses, we tend …
