Play ball! Add charges to the Field of Dreams and see how they react to the electric field. Turn on a background electric field and adjust the direction and magnitude;
Sample Learning Goals
•Explain the relation between the size and direction of the blue electric field lines to the sign and magnitude of the charge of a particle.
•Explain the interactions between two charged particles and explain why they move as they do.
•Explain what happens when you apply different external electric fields.
