1. Define centripetal force. 2. What supplies the centripetal force for (a) a satellite in orbit around the Earth and (b) the mass in uniform circular motion in this experiment? 3. An object moving in uniform circular motion is accelerating. How can this be, since uniform motion implies constant motion?
