Newton’s First Law of Motion – Inertia

Newton’s First Law of Motion – Inertia
Newton’s first law of motion states that an object at rest remains at rest will continue to be in a state of rest, and an object in motion will continue being in motion at a constant speed and in a straight line unless acted on by an external force.
Newton’s first law states that every object will remain at rest or in uniform motion in a straight line unless made to change its state by the action of an unbalanced external force. This tendency of an object to resist changes in a state of motion is known as inertia. The force acting on the body must be unbalanced since if all the external forces acting on it cancel each other out, then no net or resultant force is acting on the object. Thus, if all the external forces cancel each other out, then there is zero net force acting on the object. If there is no net force acting on the object, then the object will maintain a state of rest or move with a constant velocity.

There are very many examples of the Newton’s First Law of Motion in practice.
