Read the experiment and answer the following questions. 1. Define centripetal force. A force and therefore has-units of Newtons. Newton = kim Mass ; kilograms Sa length : meters 2. What supplies the centripetal force for (a) a satellite in orbit around the Earth, (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? 4. For an object in uniform circular motion, on what parameters does the experimental determination of the centripetal force depend when using F = ma
