In two dimensions, you can picture this as arrows drawn on the plane, where each arrow has both a direction and a magnitude that vary depending on the point’s location. In three dimensions, vector fields are often used to describe forces such as gravity, electric fields, or fluid flow, where at each point in space the field indicates the direction and strength
