question 18 (1 point)
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 to the distance traveled.

Explanation:

Distance is the total path length an object travels. Displacement is the straight - line distance from the initial to the final position. If the object moves in a straight line without changing direction, displacement equals distance. If it changes direction (e.g., moves back and forth), the displacement is less than the distance. So displacement ≤ distance.

Answer:

The displacement is either less than or equal to the distance traveled.
