A force field is a region or space where forces, such as gravity or electromagnetic forces, are in effect and interact with objects present within that region. It describes the force or influence exerted on an object due to factors such as the objects mass, charge, or other properties, and can cause objects to attract, repel, or otherwise change motions or behaviors. It can also be represented by a vector field where each point in the field shows the direction that a particle would follow in the absence of any other influences.
