According to Newton's First Law of Motion, what occurs with an object at rest?

An object at rest will tend to remain at rest until acted upon by a net force, as described by Newton's First Law of Motion. This principle conveys the concept of inertia, which is the tendency of an object to resist changes in its state of motion. In practical terms, if no net external force is applied to an object, it will not change its position or start moving on its own. This law highlights the importance of force in changing an object's state, either from rest to motion or motion to rest.

For example, a book sitting on a table will not move unless someone applies an external force by pushing it. The idea that constant conditions, such as temperature changes or fragmentation into smaller pieces, are not relevant aspects of motion without an applied net force helps clarify the concept further. Knowing this principle is vital for understanding motion and forces in various physical contexts.
