3 Newton’s First Law of Motion—Inertia 3.3 Galileo on Motion
3 Newton’s First Law of Motion—Inertia Galileo stated that this tendency of a moving body to keep moving is natural and that every material object resists changes to its state of motion. The property of a body to resist changes to its state of motion is called inertia . 3.3 Galileo on Motion

3 Newton’s First Law of Motion—Inertiathink!A ball is rolled across a counter top and rolls slowly to a stop. How would Aristotle interpret this behavior? How would Galileo interpret it? How would you interpret it? 3.3 Galileo on Motion can answer the last question!
3 Newton’s First Law of Motion—Inertia According to Galileo, when is a force needed to keep an object moving? 3.3 Galileo on Motion
3 Newton’s First Law of Motion—Inertia Newton’s first law states that every object continues in a state of rest, or of uniform speed in a straight line, unless acted on by a nonzero net force. 3.4 Newton’s Law of Inertia
3 Newton’s First Law of Motion—Inertia Newton’s first law, usually called the law of inertia, is a restatement of Galileo’s idea that a force is not needed to keep an object moving. 3.4 Newton’s Law of Inertia
3 Newton’s First Law of Motion—Inertia Objects at Rest Simply put, things tend to keep on doing what they’re already doing. Objects in a state of rest tend to remain at rest. Only a force will change that state. 3.4 Newton’s Law of Inertia
3 Newton’s First Law of Motion—Inertia Objects at rest tend to remain at rest. 3.4 Newton’s Law of Inertia
3 Newton’s First Law of Motion—Inertia Objects in Motion Now consider an object in motion. In the absence of forces, a moving object tends to move in a straight line indefinitely. Toss an object from a space station located in the vacuum of outer space, and the object will move forever due to inertia. 3.4 Newton’s Law of Inertia
3 Newton’s First Law of Motion—Inertia Blasts of air from many tiny holes provide a nearly friction-free surface on the air table. If you slide a hockey puck along the surface of a city street, the puck soon comes to rest. If you slide it along an air table where friction is practically absent, it slides with no apparent loss in speed.
