1. Nene and Dodong walked from their initial location (Point A) at the same pace and
reached the store (Point B) at the same time. What is the distance that they have
covered? What is their displacement? (Point A to Point B).
2. If Nene and Dodong continued walking and reached school (Point 9 at the same time,
what is the total distance that they have covered starting from their initial location
(Point A)? How about their displacement? (Point A to Point
3. When they reached school (Point), Dodong realized that he forgot his lunchbox.
He hurriedly returned to their initial location (Point A) to get it. What is the total
distance that he covered from the original starting point (Point A) when he returned to
the same location (Point A) to get his lunchbox back? Is the total distance that he has
covered the same with his displacement? (Point A to C and back to Point A)

Answer 1

1. To determine the distance covered, we add the distance from their initial location (Point A) to the store (Point B) for both Nene and Dodong. Since they reached the store at the same time, their distance covered is:

Distance covered = Distance from Point A to Point B = 250 meters.

Displacement is the straight-line distance from the initial position to the final position, regardless of the path taken. In this case, the displacement from Point A to Point B is also 250 meters since they directly moved from Point A to Point B without changing direction.

2. If Nene and Dodong continue walking and reach the school (Point C) at the same time, we need to consider the distance from the store (Point B) to the school (Point C) as well. The total distance covered is the sum of the distance from Point A to Point B and the distance from Point B to Point C:

Total distance covered = Distance from Point A to Point B + Distance from Point B to Point C = 250 meters + 250 meters = 500 meters.

The displacement from Point A to Point C is a straight-line distance, so it is the same as the displacement from Point A to Point B, which is 250 meters.

3. When Dodong realizes that he forgot his lunchbox at school (Point C) and returns to the initial location (Point A) to get it, the total distance covered is the sum of the distance from Point C to Point A (the return journey) and the distance from Point A to Point C (initial journey):

Total distance covered = Distance from Point A to Point C + Distance from Point C to Point A = 500 meters + 500 meters = 1000 meters.

However, the displacement is still the straight-line distance from Point A to Point C, which is 250 meters.

4. Distance refers to the total length of the path covered by an object, taking into account any changes in direction. It is a scalar quantity that only considers magnitude.

Displacement, on the other hand, is the shortest straight-line distance from the initial position to the final position of an object, irrespective of the path taken. It is a vector quantity that includes both magnitude and direction.

In summary, distance considers the entire path traveled, while displacement focuses on the initial and final positions, regardless of the path followed.
