1. Consider a point moving at a constant speed v on a circle of radius r. What is the relation between v, r, and the rotation frequency, f? 2. Show that the centripetal acceleration relation, ac = v2/r, can be put into the form ac = [2-f]2.r. 3. In this experiment you will determine g from experimental values of m1, M2, r, and f. The frequency f is found by dividing the number of revolutions by the time for those revolutions. Assume g = 9.80 m/s2, take m1 = 500 g, M2 = 800 g, and r = 18 cm, and calculate the frequency f, and then the time for 50 cycles. 4.) Referring to the equation g = m1- [2-f]2-r/M2, what do you expect the frequency to vary with the radius of the rotational motion?
