In this project, you will develop a model of two objects interacting through electric fields. The model must show the relationships between the objects that make up the system, such as the forces between them and any changes in the energy of the objects due to their interaction. Your model should also show that if the objects change their relative positions, the energy stored in the fields changes.
Background
Charged particles exert forces on one another. Particles with like charges repel each other, and particles with opposite charges attract each other. This repulsion or attraction can be described as the electric force. Coulomb's law describes the force between charged particles. It states that the electric force between two particles is proportional to the product of the magnitudes of their charges (q1 and q2) and inversely proportional to the square of the distance between them (r):
Fe = kq1q2/r2
(The term k represents a constant.)
Note that as the distance between two charged particles increases, the electric force between them decreases. Also note that, like the gravitational force, the electric force can act at a distance. In other words, there can be an electric force between two charged particles that are not in contact.
The force is carried from one charged particle to another by the field that surrounds each charged particle or group of charged particles, which is called the electric field. The electric field of a charged particle is affected by the electric fields of other charged particles.
An electric field is a vector force field, so it has both a magnitude and a direction. The magnitude of an electric field is expressed as E = F/q, using the unit of newtons/coulomb (N/C). Electric field lines are used to show the magnitudes and directions of electric fields. These lines are drawn so that they point away from positive charges and toward negative charges. Below is an example of an electric field diagram.

How strong is the electric field from the charge q that is affecting charge q0?
Your model should show two objects interacting through electric fields and should also account for the electric force carried by the fields and any energy changes occurring when the objects change positions. What types of models (for example, diagrams or computer simulations) would best represent this interaction?
You will need to work with your teacher to develop your model. You can use the electric force and charge virtual lab in the study to help you. Materials needed should be readily available to you. After the plans for your model are approved, you will need to develop and use the model. This will enable you to determine how well it works. You should then make changes so that your model more accurately represents the system.
