- Electric Charges
- Electric Field
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. (Kevin Costner not included).
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.
