Suppose that an object travels from one point in space to another. Make a comparison between the displacement and the distance traveled.
The displacement is either greater than or equal to the distance traveled
The displacement is always equal to the distance traveled
The displacement is either less than or equal to the distance traveled
The displacement can be either greater than, smaller than, or equal tot the distance traveled.
