Question

Can displacement be zero? If yes, give two examples of such situations. Five Mark Questions

Answer 1

Answer:

yes, displacement can be zero. displacement is the shortest distance between initial position and final position. if both are same, then least distance would be zero.

for example- if you travel from your home to school and back to home, distance would be twice the distance between your home and school. but, as the initial and final position are same and distance between your home and home is zero, hence displacement is zero.

Answer 2

Answer:

Displacement can be zero even when distance is not zero. Consider two points A and B such that AB=5m.

When car travels from A to B then back from B to A ,distance = 5+5=10m.

When we throw a ball up in the air for whole of the journey covered by ball displacement would be zero as the ball come back to it'soriginalplace.

Displacement = minimum distance between final and initial position.

hope it helps you ✌
