In an investigation of two electrically charged objects, a student models the interaction through a computer simulation. The simulation shows that as one object approaches the other, the system's kinetic energy increases. What could explain this observation? Mark only one oval.

• The objects are attracting each other, converting potential energy into kinetic energy.

• The objects are moving further apart, decreasing the overall energy in the system.

• The potential energy is increasing, converting kinetic energy into electric potential.

When analyzing a model of electric field interactions between two oppositely charged objects, how would the force and potential energy change as the objects move closer together?

• The force increases, but the potential energy decreases as they attract each other.

• The force decreases, and the potential energy remains constant.

• The force remains the same, while potential energy decreases.
