Newton’s First Law of Motion is also known as the Law of Inertia. This law states that an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity, unless acted upon by a net external force.
The concept of inertia is critical here, as it refers to the tendency of objects to resist changes in their state of motion. In practical terms, this means that it takes some force to get an object to start moving if it’s at rest, or to stop it if it’s already moving. This principle is evident in everyday experiences, like how passengers lurch forward in a car when it suddenly stops.
Understanding the Law of Inertia helps us comprehend how forces interact with objects, forming the basis of classical mechanics and influencing various fields of science and engineering.
