Newton's first law of motion, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity, unless acted upon by an external force. In other words, an object will continue to do what it is doing unless a force acts upon it to change its motion. This law is often summarized as "an object in motion tends to stay in motion, and an object at rest tends to stay at rest."
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
