NEWTON'S FIRST LAW AND INERTIA:
All the material bodies possess the property of opposing any alter in the state of rest or uniform motion when some external force is applies upon them. It means that the state of rest or uniform motion does not alter by itself unless some external force acts upon it; which is same to the statement of first law of motion. That is why the first law of motion is also known as 'law of inertia'.
