Is force ever negative
WebAs a result, the work done by a force can be positive, negative, or zero, depending on whether the force is generally in the direction of the displacement, generally opposite to the displacement, or perpendicular to the displacement. WebForces are not negative or positive. Sign indicates direction. That's it. It is unrelated to any physical significance and that as well depends on convention taken. Gravitational force if attractive between two positive mass or two negative mass and replusive between one negative and one positive mass. Sahil Prajapati
