Lesson Objective

Establish the foundational concept of electric charge as a fundamental property of matter and introduce the inverse-square law relationship governing electrostatic interactions.

How does the matter around us acquire a net electric charge?

What happens to the structural integrity of an atom if the distance between its protons and electrons is doubled?

How does the mathematical relationship of Coulomb's Law mirror Newton's Law of Universal Gravitation, and where do they differ?

Coulomb
Electrostatic Constant
Inverse-Square Law
Polarization

HS-PS2-4: Use mathematical representations of Newton’s Law of Gravitation and Coulomb’s Law to describe and predict the gravitational and electrostatic forces between objects.

HS-PS3-5: Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.

Mathematically predict the electrostatic force between two charged objects using Coulomb’s Law and model how changing charge or distance alters that force.

Static electricity build-up on the surface of a moving vehicle attracts neutral dust particles from the air. This concept also explains how photocopiers (xerography) use static charges to attract ink toner to paper.
