Question

When the final position of an object in motion coincides with its initial position:

A. Both displacement and distance are 0
B. displacement is zero but distance is not zero
C distance is zero but displacement is not zero
D distance and displacement both are non zero​

Answer 1

Answer:

Answer

The displacement is the shortest distance between initial and final position. When final position of a bodycoincides with its initial position, displacement is zero, but the distance travelled is not zero.

Answer 2

Answer:

When the final position of an object in motion coincides with its initial position: B. displacement is zero but distance is not zero

Explanation:

• Distance: Distance is the actual length between initial and final position. It is a scalar quantity.
• Displacement: Displacement is the shortest path between initial and final point. So it can be zero. It is a vector quantity.
• Example: If a person covers one round in a circular ground. If the initial and final point matches,

then distance covered = actual path covered by him = circumference of the circle.

Displacement = shortest length between initial and final position = 0

∴ Here displacement is zero but distance is not zero.
