Coulomb’s Law: Electric Force, Field and Potential

In this topic, you will learn about the forces between electric charges and how the interaction of charges within electric fields is similar to the interaction of masses within gravitational fields.

Essential Questions:

• How is the force between charged objects described mathematically? 
• How does an electric field develop between charged objects?
• What is electric potential? 
• How is the movement of charges in electric fields similar to the movement of mass in gravitational fields? 
• How is the movement of charges in electric fields different than the movement of mass in gravitational fields? 
• How do you determine the difference in electric potential between charged particles in an electric field?
