In general physics, a force field is a vector field representing the gradient of a potential. The vectors that are the values of a force field are forces, and so measured in units of force such as newtons and pounds-force.

A force field can exist in the surround­ing space of a mass, electric charge, or magnet, so that something new brought to the environment will experience a force.
