Question

If on a round trip you travel 6 km and then arrive back home (a) What distance have you travelled?
(b) What is your final displacement?

Answer 1

$\huge{\star}{\underline{\boxed{\red{\sf{Answer :}}}}}{\star}$

Given :-

If on a round trip you travel 6 km and then alive back home.

To Find :-

Distance covered

Final displacement

Solution :-

Case 1 :-

We traveled 6 km when going to trip and 6 km when coming back home.

So,

Distance = 6 km + 6 km

Distance = 12 km

$\huge{\boxed{\blue{\sf{Distance = 12 \: Km}}}}$

Case 2 :-

We know that,

Displacement is the shortest path from initial position to final position.

So, when we came back home displacement became zero(0).

Displacement = 0

$\huge{\boxed{\blue{\sf{Displacement = 0 }}}}$

Answer 2

$\large{\underline{\underline{\tt{ \pink{S} \blue{O} \red{L} \green{U} \orange{T} \purple{I} \pink{O} \blue{N} \red{:-} }}}}$

⬇️(a) Distance travelled = 6 km

⬇️(b) Displacement = zero(since final position is same as initial position)
