Fields, directions, and equipotentials

Side-by-side diagrams of a positive point charge with outward electric field lines and a point mass with inward gravitational field lines, both with concentric equipotential circles meeting the field lines at right angles

A field is a region of space where an object experiences a force without contact. In an electric field, the direction is defined by the force on a small positive test charge, while in a gravitational field, it is the force on a small test mass.
