Answer:
inertia
Step-by-step explanation:
The period of inertia is one of the characteristics of the Phase 2 of the Punctuated Equilibrium Model.
The punctuated-equilibrium model of group development states that it usual for a group to move forward during a period of sudden change after passing through a long periods without change.
At the Phase 2 of the Punctuated Equilibrium Model , the group seems to stands still or becomes locked into a fixed course of action. This phase is therefore referred to as a phase of inertia or a period of inertia.
