You are kicking your soccer ball back and forth on a soccer field. You kick the ball forward for 10 m. You turn completely around and kick the ball back for 20 m. Your turn again and kick the ball forward for 40 m. What is your distance and what is your displacedment?

1.) Total distance = 70 m

2.) Total displacement = +30m

Explanation:

Distance is a scaler quantity. That is, we will be concerned about its magnitude only and not direction.

Total distance = 10 + 20 + 40 = 70 m

While displacement is a vector quantity. We will consider both the magnitude and its direction.

Forward direction will be positive while backward direction will be negative

Total displacement = +10 - 20 + 40

Total displacement = +30 m
