Recall that we talk about work as the amount of force in the direction of an object's displacement multiplied by the displacement. No displacement, no work. Work is positive if F and Δ x (or d x) point in the same direction and negative if F and Δ x (or d x) point in opposite directions.

Distance and displacement are commonly confused terms in physics that are important to get correct. Distance is a scalar quantity , the total distance traveled by an object; displacement is a vector quantity , the shortest path in a straight line between the starting position and final position.

Note that distance travelled is a non-negative quantity while displacement is a signed quantity. The object's displacement is positive, respectively negative, if its final position is to the right, respectively to the left, of its initial position. Displacement may or may not be equal to distance travelled. Distance Between 2 Points.
