Displacement
Summary: Displacement is defined as how much an objects position changes (using only its starting position and final position). It is a vector quantity meaning it has both a direction and magnitude. Displacement Also has a positive or negative direction depending on its direction of motion. Lastly Displacement is different than distance. For example If an object goes around a track its distance traveled is scalar and would be 400 m but since when going around a track you end in the same place you start the displacement of the object would be zero.

| By looking at this graph you can tell that the objects displacement after 5 seconds is 50 meters away from the origin because its final position minus initial position (5-0) equals 5. |

| If an object where to run 20 laps around this track its distance would be 5 miles but since the object would start and finish at the same position, It's displacement would be zero (the final position-initial position)
