Electric charge is the property that allows an object to exert a force on another without touching. When an object has electric charge, it creates an electric field in the space around it. This field reaches out and interacts with other charges, pulling them closer or pushing them away even when there is no contact. The strength of this force depends on how much charge each object has and how far apart they are, described by Coulomb’s law. The idea behind the field is just a way to describe how the force reaches across distance, but the fundamental property enabling the interaction is the electric charge itself.
