Cliff Notes I. Inertia A. Inertia: what makes an object resist a change in motion B. More mass = more inertia C. Examples 1. Football player blockers are bigger (have more mass-->more inertia) because they don't want to move Wide receivers are smaller (less mass-->less inertia) because they need to move quickly 2. Cars are smaller than buses (have less mass-->less inertia), so they can turn more quickly 3. Long boards are harder to maneuver than short boards (have more mass-->more inertia), so it's harder to turn them II. Newton's First Law: Law of Inertia A. Objects in a state of rest, or in a state of motion at constant speed in a straight line, will continue in that state unless a force acts on it Attachments Newton's First Law Activities - activities that help show Newton's First Law in action |
