Question

if on a round trip you travel 6 km and then arrive back home calculate your displacement after completing the trip​

Answer 1

In the question it is given that on a round trip, I travel 6 km and then arrived back home.

Here, since, the starting point is home, and the final point is also home, there is $\textbf{no displacement}$.

Hence, the answer is :-

$\underline\textbf{Displacement = 0 km}$

→ If the initial and final points are same, there is no displacement.

→ There is a difference between distance and displacement. Distance is the actual path covered, whereas the displacement is the shortest path between the final and initial positions.

→ Distance ≥ Displacement and displacement ≤ distance.

→ Displacement is calculated by velocity and time, whereas distance is calculated by speed and time.

→ Displacement is vector quantity, distance is scalar quantity.

Answer 2

Question -

If on a round trip you travel 6 km and then, arrive back home calculate your displacement after completing the trip.

Solution :

It is given that the person arrived back home after the trip , so it means that there happens no displacement.

So the displacement = 0

What is displacement?

Displacement is the measurement of shortest path length measured from the initial position to the final position of an object .

The displacement has direction and magnitude both.

The displacement of a moving body can be positive, negative or zero.
