Chapter 3 Explaining Motion Lecture #3: Agenda: 1. Inertia 2. Newton’s First Law of Motion 3. Force 4. Vectors Galileo was the first to suggest that constant-speed; straight-line motion was just as natural as at-rest position. This property of remaining at rest or continuing to move in a straight line at a constant speed is known as inertia. 1. Inertia Inertia is the property of matter to maintain a constant velocity unless acted upon by an unbalanced force. This velocity can be zero, in which case the object remains at rest. Inertia is related to the mass and size of an object. Heavier an object and larger the size, more is inertia. For example, a mighty solid sphere needs lot more force to move, and if it is moving on a flat frictionless surface, it is harder to stop. If something is at rest, an interaction of some kind is required to get it moving. Conversely, if an object is in motion, it needs a net force to be stopped. 2.
