The Inertia setting is the resistance of any physical object to any change in its state of motion, including changes to its speed and direction. In other words, objects at rest will remain as such.
By setting different Inertia values, you can create soft cloth that will continue moving in a certain direction until another force causes it to change.
Here is a soft cloth (pinned by two corners) that stops abruptly at a certain time.
Set various inertia values to determine if you want the un-pinned part of the cloth to keep moving in different levels when the entire cloth stops.

Inertia = 0 The soft cloth does not go beyond the stop position. |
Inertia = 10 The soft cloth goes slightly beyond the stop position. |
Inertia = 20 The soft cloth goes well beyond the stop position. |
