DISTANCE | DISPLACEMENT

2.      15m.               5m. N

3.      10m.                 0m.

4.      7m.                 5m. NE

5.      8m.                 8m. W

6.      14m.                10m. SW

Explanation:

Distance is a scalar quantity, which means the direction does not matter. Displacement, on the other hand, is a vector quantity, which means direction should be included in every solution. Think of distance as a measure of how far you have walked, while displacement is how far you travelled from where you started.

For distance, simply add up the first move and the second move, regardless of their direction. (For example, number 2: 10m N + 5m S = 15 m)

For displacement, consider the directions. If the two directions are opposite of each other (number 3), subtract the two numbers and whichever direction has the greatest value is the final direction (for example in 1, east direction has greater value than west. Therefore, the final direction would be east.)

If the two movement is on the same direction, simply add up.

If the two movement forms a right triangle (number 4 and number 6), the Pythagorean Theorem should be utilized. The final direction can be computed using , with c being the displacement and "a" and "b" being the values for the first and second movement. The direction of the displacement is then the combination of the first and second move's directions. For example, you travelled North, then travelled East, your displacement is Northeast, or NE.
