Question

*A bird reached 500 m in 5 minutes. He took a round around the tree and came back to his place. How much is the displacement?*

1️⃣ 500 m
2️⃣ Zero m
3️⃣ 2500 m
4️⃣ 1000 m​

Answer 1

Answer:

0 displacement because final position is same as initial position

Answer 2

The displacement for the bird is (2) zero m.

• Displacement is defined as the absolute distance or straight path distance from the initial position to the final position.
• If say an object moved 2 m west and then 4 m north then the distance, in this case, will be (2+4)=6m but the displacement here will be $\sqrt{2^2+4^2}$=root20.
• Similarly if an object travelled any distance from the initial position to the final position but it came back to where it was then the displacement is counted as 0.
• Hence, in this case, the bird also did the same so the displacement is 0 and the correct option is (2).
