What is the Defination and difference Position and Displacement

Difference between distance and displacement in physics and Definition

 Define Position 

The position x of a particle on an x axis locates the particle with respect to the origin, or zero point, of the axis.The position is either positive or negative, according to which side of the origin the particle is on, or zero if the particle is at the origin.The positive

direction on an axis is the direction of increasing positive numbers; the opposite direction is the negative direction on the axis.

"To locate an object means to find its position relative to some reference point, often the origin (or zero point) of an axis such as the x axis .The positive direction of the axis is in the direction of increasing numbers (coordinates), which is to the right.The opposite is the negative direction."

Define  displacement

"A change from position x1 to position x2 is called a displacement "

The displacement _x of a particle is the change in its position: x = x2 - x1.

Displacement is a vector quantity. It is positive if the particle has moved in the positive direction of the x axis and negative if the particle has moved in the negative direction.
