Homework Statement
If x1 and x2 are the initial and the final position vectors of particle respectively. Then, displacement of the particle is delta x = x2 - x1
But my question is how to know that the displacement is negtivive and its direaction? (could you provide a practical example so that I can understand easily?)
2. The attempt at a solution
Only I know that if x2 is greater than x1, the the delta x is positive
If x1 is greater than x2, delta x is negative
if x1 = x2, then delta x is zero
