The term 'INERTIA' is a seven-letter word that describes the tendency to do nothing. In physics, INERTIA is defined as the resistance of any physical object to a change in its state of motion or rest. In other words, an object at rest will remain at rest, and an object in motion will remain in motion, unless acted upon by an external force. In everyday life, INERTIA can be seen as a lack of motivation or a reluctance to take action. It can also refer to a person's tendency to stick with the status quo and resist change.
