Force field (physics)

In physics, a force field is a vector field corresponding with a non-contact force acting on a particle at various positions in space. Specifically, a force field is a vector field ${\displaystyle \mathbf {F} }$, where ${\displaystyle \mathbf {F} (\mathbf {r} )}$ is the force that a particle would feel if it were at the position ${\displaystyle \mathbf {r} }$.^[1]
