The spoken lesson
"Friction is a force that opposes relative motion or attempted motion. Static friction can prevent an object from beginning to slide. Sliding friction acts while surfaces move past one another. Rolling resistance affects wheels and balls, and drag acts through air or water. Friction helps shoes grip the ground, hands hold objects, pencils write, and brakes slow vehicles. Friction can also create heat, wear materials, and waste useful motion. Surface material, pressure, moisture, lubrication, and other conditions affect friction. Friction resists motion, creates grip, and changes movement into heat." DESIGN REQUIREMENTS: Use dry safe materials and slow movement. Avoid oil spills, slipping children, high-speed vehicles, roughness oversimplification, or dangerous ramp testing.
