Activity 8.4 Class 9 Science Chapter 8 Motion
What activity asks?
The activity asks us to find the magnitude of displacement between Bhuvneshwar and New Delhi.
The magnitude of displacement between Bhuvneshwar and New Delhi is around 1400 km.
The magnitude of displacement is the shortest possible distance between two points. The roads of a city are not linear and change its shape as per terrain. For example, while climbing a mountainous region road is circular and so on.
The only possible shortest distance is through the air.
We can get the magnitude of displacement by placing a thread between the point on a road map and compare it with the scale given on the map.
Here we get around 1400km only. While by road distance it is 1850km.
The city shows that magnitude of displacement between two points is either equal to or shorter than its distance.
