when the displacement is -ve?

Dear student
Displacement is denoted by a vector with its head at the final position & tail at the initial position. The direction of this vector is postive if it is directed along + axis, could be either +x- axis or + y axis.
The direction of this vector would be negative, if it directed along - axis, could be either - x axis or - y axis.
 
For example, for a ball thrown vertically up & caught at a point higher than initial position, will have its displacement vector diercted along + y axis. Displacement is positive.
For a ball thrown vertically up & caught at a point lower than initial position, will have its displacement vector diercted along - y axis . Displacement is negative.
 
We hope that clarifies your doubt.

During calculation of acceleration due to gravity above the surface of earth if we assume that there is an external force opposite to that of Earth's gravity then the cos angle will be 180 between the two forces which is negative(-1), if we put the value in the equation of dw = F.dx then the final value of potential energy is positive which is not possible.how and why??
