Objective: (4 Pts): Experimental Data and Analysis (20 Pts): For each graph produced in this lab, take a screenshot and insert it into this worksheet. Show work for all calculations. Part 1: Measuring g without friction Fill in the parameters that you chose to use in your experiment. Kinetic Friction Coefficient: ????k 0.0 Static Friction Coefficient: ????s 0.0 Angle of Incline: incline 0.0 Sliding Mass: m1 0.5 kg Hanging Mass: m2 0.5 kg Hanging Mass Init Velocity: ????init 0 m/s Results from Part 1 Value of gravitational acceleration: ???? g = (2h/t^2) = (2*1.0)/(0.45)^2 = 9.88 m/s^2 %Error from known value (9.81 m/s2) ((9.88-9.81)/9.81)*100= 0.71% Insert your graphs for Part 1: Part 2: Measuring g with friction This experiment is much more realistic and demonstrates the methods used in the real life version of the lab that cancel out friction, and allow an accurate measurement of "g". Fill in the parameters that you chose to use in your experiment. Use the same Masses and Velocity as you used in Part 1. Kinetic Friction Coefficient: ????k 0.3 Static Friction Coefficient: ????s 0.6 Angle of Incline: incline 0.0 Sliding Mass: m1 0.5 kg Hanging Mass: m2 0.5 kg Hanging Mass Init Velocity: ????init 0 m/s Results from Part 2 Acceleration while moving left: ????left 0.3*0.5*9.81= 1.4715 N T= 0.5*9.81= 4.905 N 4.905-(0.5*9.81)-1.4715 =-0.5aleft =(1.4715*2)/1= 2.943 m/s^2 Acceleration while moving right: ????right 4.9054.905+1.4715=0.5????right (1.4715*2)/1= 2.943 m/s^2 Average left
