Question

a person starts from the house and travels a circular distance of 15 km around a walled city before returning back. what is the distance and displacement​

Answer 1

Distance & Displacement

The answer is short. But first let's know about distance and displacement before knowing the answer.

Distance is a scalar quantity. It can never be negative or zero. It will always be positive. And, Displacement is a vector quantity. It can be positive, negative or zero depending on the question.

Now, it's time to know the answer.

The distance travelled by the person is 15km and the displacement is 0 because the end and starting points are same. [tex][/tex]

Answer 2

Answer:

Question :-

☯ A person starts from the house and travels a circular distance of 15 km around a walled city before returning back. What is the distance and displacement.

Given :-

☯ A person starts from the house and travels a circular distance of 15 km around a walled city before returning back.

Find Out :-

☯ What is the distance covered and displacement.

Solution :-

☣ In case of Distance covered :-

✍ Distance covered = Total path covered = circumference

➙ Distance Covered = 15 km

☣ In case of Displacement :-

✍ Displacement = Shortest distance between initial and final position

➙ Displacement = 0

EXTRA BRAINLY SHOTS :-

Displacement :

• It is the linear distance between the initial and final positions of a body.
• It has both magnitude and direction - it is a vector quantity.
• Its SI unit is m.
• Formula - Velocity × Time.

Distance :

• It is the actual length of path followed by the body while moving between two positions.
• It has only magnitude - it is a scalar quantity.
• Its SI unit is m.
• Formula - Speed × Time.
