​Newton's first law deals with objects in a static or uniform state of motion. Newton thought, acting on an object if the resultant force is zero, the originally dormant static object, originally moving objects to the original direction of uniform motion. This means that all objects naturally tend to stay the same. All objects resist changes in their motion until they are acted upon by an unbalanced force. The phenomenon that an object resists a change in its motion is called inertia.
