also known as Law of Inertia, An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
This is one of the three laws of motion formulated by Sir Isaac Newton and is the foundation of classical mechanics. The Law of Inertia describes the tendency of objects to resist changes in their state of motion - whether that be at rest or moving in a straight line at a constant speed. An object will continue in its current state unless an external force is applied to it.
For example, if you roll a ball across a flat surface, it will keep moving until friction or another force stops it. Similarly, if you push a stationary object, it will only start moving if there is enough force to overcome its inertia.
Understanding the Law of Inertia is essential for understanding the behavior of objects in motion and is crucial in various fields of science, engineering, and everyday life.
