Question

Find the distance covered and its displacement, if a body moves 30 km North from its starting position, then turn return back South and travels 10 km?​

Answer 1

Given:

A body moves 30 km North from its starting position, then turn return back South and travels 10 km.

To find:

• Distance
• Displacement

Calculation:

Distance is the total path length traversed by an object.

• So, distance = 30 + 10 = 40 km.

Displacement is the shortest length between the starting and the stopping point.

• So, displacement = 30 - 10 = 20 km.
• In case of displacement, we also need to mention the direction. In this case, direction will be North (N).

So, displacement is 20 km North.
