An object at rest will remain at rest and an object in motion will remain in motion until and unless it is acted upon by an external force. This is Newton's –
Newton's first law of motion - sometimes referred to as the law of inertia-states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.
