Activity 1: Introduction to Electric Fields

Watch this  video from Khan Academy ( https://www.khanacademy.org/science/physics/electric-charge-electric-force-and-voltage/electric-field/v/electric-field-definition )  to understand the motivation for the concept of electric field.

This exercise provides a brief introduction to the concept of electric field using a simulation from the Phet site. Before using the simulation watch this short video that explains how to set it up. Then go the questions. You can launch the simulation below or, if you prefer, you can launch it directly here.
