activity 8.4 class 9 science motion

Explanation:

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.

Inference:

The city shows that magnitude of displacement between two points is either equal to or shorter than its distance.
