Solution :
This is an example of Newton's first law: An object at rest will remain at rest, and an object in motion will remain in motion in that direction unless acted upon by an outside force.

Inertia is effectively nature’s way of trying to avoid change. This explains why the box is hard to move while it is still; it requires a change to get it to move from rest to moving.
