Question

An ant moves from A to B and then comes back to point A. Find the distance (d) and displacement (s) of the ant in this entire journey.

• A. d = 10 m, s = 0 m
• B. d = 0 m, s = 0 m
• C. d = 10 cm, s = 10 m
• D. d = 5 m, s = 10 m

Answer 1

The correct option is A

d = 10 m, s = 0 m

Step 1: Fix the starting point of ant i.e. A.

Fix the finishing point of ant i.e. A itself.

Distance = Path length = AB + BA = 5 + 5 = 10 m

Displacement = Shortest distance between starting and finishing point.

In this case they are same so 0 m.
