According to Newton's First Law, what will happen to an object at rest?

Newton's First Law, often referred to as the law of inertia, states that an object at rest will remain at rest unless acted upon by an unbalanced force. This principle signifies that in the absence of external forces, an object will not change its state of motion. Therefore, if an object is stationary, it will not start moving until a force that is not balanced by another force acts upon it.

For example, a book lying flat on a table will stay in that position until someone pushes it (an external unbalanced force) or some other force (like gravity, which is balanced by the normal force from the table) acts on it. This law highlights the concept of inertia, where objects tend to resist changes to their state of motion, whether they are at rest or in motion.
