Gravitational and electric fields are both examples of force fields that act over a distance. Gravitational fields are regions around a mass where another mass experiences an attractive force. The force is proportional to the product of the masses and inversely proportional to the square of the distance between them. Gravitational fields are always attractive. Electric fields exist around charged particles. A positive charge creates a field that repels other positive charges and attracts negative charges. The electric force depends on the charge and the distance between charges and can be either attractive or repulsive. Both fields follow an inverse square law and can be represented by field lines.
