As the distance between two charged particles increases, the force of attraction (increases/decreases). This is a(n) (direct/indirect) relationship. Explain your evidence and reasoning with observations from the simulation.

decreases.

direct.

Explanation:

when you have two objects which are far apart from each other,  when the distance increases the forces of attraction decreases and vice versa when the distance decreases the forces of attraction also increases.

this is a direct relationship, from careful observation and monitoring of the simulation, a pattern is noticeable by which an increase in one variable causes an opposite effect on the other variable.
