LAB # 16 Circular Motion Introduction : We wish to study the relation: F c = Ma c (Newton's 2nd Law) (1) for a mass M in uniform circular motion. Recall that in this case ac can be calculated from any of these expressions; a c = v 2 r = ! 2 r = 4 " 2 T 2 r (2) where v is the velocity, r the radius, ω the angular velocity and T the period. Since T is easiest to measure directly, we can focus on the last expression for your experiment. NOTE : You will define centripetal acceleration and verify the expressions (above) given for them. ALSO use the prepared tables in the computer program for the values of T, and mg to be measured. The r is fixed in this experiment. Find the mass of the black bob on the scale. Apparatus : Circular motion apparatus, Computer, ULI, ROTATION APPLICATION, then the ROTATIONAL (ANALYSIS) APPLICATION, photogate, Scale and slotted weights, Meter stick. Procedures : The apparatus is shown in Figs. 1, 2 and 3. Note that the photogate must be set-up so that it will record the movement (Period) of the “black stick” attached to the shaft of the Circular motion apparatus as well as attached to the ULI and computer. 1. Open the application ROTATION on the computer. Next examine the Circular Motion Apparatus. The vertical shaft can be made to rotate at a rather constant rate (after some practice) by a
