-To prepare for this lab, you should review the material in the online Lecture Notes and Lecture Videos for PHY 121 in Fall 2012.  You will also find to be helpful sections 7.4 and 7.5 of the textbook //Knight, Jones and Field (2nd ed.)//, (abbreviated KJF2). ​ If you don't have it, a copy is available in the PHY 121/2/3/4 Help Room, A-131 Physics. ​ It's bolted to the table near the blackboards. ​   ​+To prepare for this lab, you should review the material in the online Lecture Notes and Lecture Videos for PHY 121 in Fall 2013.  You will also find to be helpful sections 7.4 and 7.5 of the textbook //Knight, Jones and Field (2nd ed.)//, (abbreviated KJF2). ​ If you don't have it, a copy is available in the PHY 121/2/3/4 Help Room, A-131 Physics. ​ It's bolted to the table near the blackboards. ​   ​
  
 In Part I you measure the angular acceleration $\:​\:​\alpha$ of an object, a rotating table (also called "​platform"​ below), caused by a known externally applied torque. ​ From this measurement you can obtain the moment of inertia $\:\:I$ of your rotating table. The equation that relates the net torque $\:​\:​\tau_{net}$ to the moment of inertia and the angular acceleration of a rotating object is (cf., Eq. 7.15 on p. 214 of KJF2): ​ In Part I you measure the angular acceleration $\:​\:​\alpha$ of an object, a rotating table (also called "​platform"​ below), caused by a known externally applied torque. ​ From this measurement you can obtain the moment of inertia $\:\:I$ of your rotating table.
