This interactive tutorial is intended to help students comprehend the underlying relationships among electrical force, quantity of charge, and separation distance. It takes learners through a strategic analysis of using Coulomb's equation to solve problems. Problem-solving steps are explicitly shown in three examples, then a set of 7 problems are introduced (with answers available for immediate feedback).

This page is part of The Physics Classroom tutorials for students of introductory physics. SEE RELATED ITEMS on this page for a link to a closely related tutorial on inverse square relationships by the same author.

This resource is part of 3 Physics Front Topical Units.

Topic: "Static" Electricity
Unit Title: Electric Force

Electric force and gravitational force are two types of non-contact forces. Coulomb's Law equation for electrical force bears a strong resemblance to Newton's equation for universal gravitation. Both show an inverse square relationship between force and separation distance. This interactive tutorial will help K-8 science teachers gain insight about the nature of electrical forces, which, unlike gravitational forces, can be either attractive or repulsive.

Topic: "Static" Electricity
Unit Title: Electric Force

This interactive tutorial, part of The Physics Classroom, does a first-rate job of explaining the concepts underlying Coulomb's Law.

Topic: Electricity and Electrical Energy
Unit Title: Electric Force and Coulomb's Law

Middle school teachers may want to revisit Coulomb's Law before doing a unit on electricity. This interactive tutorial is very beneficial in explaining force as a vector quantity, how to determine the direction of electrical force vectors, and content support in calculations related to Coulomb's Law. It is part of The Physics Classroom collection.
