          Description
        
        Visualize the electrostatic force that two charges exert on each other. Observe how changing the sign and magnitude of the charges and the distance between them affects the electrostatic force.
        
          
            Sample Learning Goals
          
          
            - Relate the electrostatic force magnitude to the charges and the distance between them
 - Explain Newton's third law for electrostatic forces
 - Use measurements to determine Coulomb’s constant
 - Determine what makes a force attractive or repulsive
