These forces are caused by electric charges in matter. Objects can have positive, negative, or neutral charges. Electric forces can attract or repel, depending on the charges involved. The strength of the force depends on the charge and distance between objects.

An insulatoris a material that resists the flow of electrons, so it does not allow electric current to pass through it. Learn about how conductors and insulators work and how they are effected by changes in electrical current.

However, objects can develop a static net charge if they pick up extra electrons or lose some electrons. This can happen through friction. Objects with opposite net charges attract, and objects with like net charges repel. It's also possible for a net neutral object to be attracted to a charged object. This happens because atoms near the surface of the neutral object become polarized.
