Circular MotionEyes You'll Never See: The Many Uses of Artificial SatellitesFrom phone calls and GPS to hurricane forecasts and Hubble's view of deep space, every satellite mission comes down to the same physics: gravity providing centripetal force. Students see how altitude decides everything — and choose the right orbit for a real engineering scenario. 3 multiple-choice and 3 extended-response questions, built as an interactive web page.Open Reading Passage
Circular MotionFalling Sideways: The Hidden Physics of Turns, Loops, and Orbits
Orbit is continuous falling: gravity pulls inward while sideways velocity carries the satellite around Earth.Why does your body slide toward the door when the car turns? How does a motorcyclist stay glued to a vertical loop, and why does the Moon never crash into us? One idea — centripetal force — ties together car turns, loop-the-loops, orbits, and the tilt of a leaning bicycle. 3 multiple-choice and 3 extended-response questions.Open Reading Passage
