The tendency of an object to change its acceleration

Objects in motion stay in motion, objects at rest stay at rest
|
Detailed explanation-1: -Newton’s first law states that an object in motion tends to remain in motion with same speed and direction, or object at rest tends to be at rest, until and unless an external unbalanced force acts on the object. This tendency of an object to resist its initial state of motion is called inertia.
Detailed explanation-2: -Inertia is the resistance of any physical object to any change in its state of motion. This includes changes to the object’s speed, direction, or state of rest.Inertia is also defined as the tendency of objects to keep moving in a straight line at a constant velocity. examples of inertia of rest.
Detailed explanation-3: -The tendency of a body to resist any change in its motion (speed or direction) – in other words, to resist any change in its acceleration – is called its ‘inertia’. Mass can be thought of as a measure of a body’s inertia. Inertia means ‘reluctance to change’.
