In physics a force field is a vector field that describes a non-contact force acting on a particle at various positions in space. Specifically, a force field is a vector field F→{\displaystyle {\vec {F}}}, where F→(x→){\displaystyle {\vec {F}}({\vec {x}})} is the force that a particle would feel if it were at the point x→{\displaystyle {\vec {x}}}.
