LAB REPORT FOR M2 EXPERIMENT: FREE FALL VI-1: For this section of the lab I included the time (t) it took for the metal ball to free fall based on its height from the ground (d). Since there were 6 different drops for the smaller ball and 1 drop for the larger ball, I have included 7 tables that contain each individual time (t) as well as the average time ( _ t ), time squared (t 2 ) the standard deviation of time squared ( 2 t σ ) and the average time squared ( 2 t ). For tables 6 and 7 I included the standard deviation of time ( t σ ) as well. In order to calculate all of these values I utilized Microsoft EXCEL to find: t σ , 2 t σ , _ t , t 2 and 2 t . The formulas for these calculations are below the tables: Drop 1: d = 0.262m Drop 2: d = 0.501m Trial # t (sec) t 2 (sec 2 ) 1 0.228 2 0.05208 2 0.228 4 0.05217 3 0.228 4 0.05217 4 0.228 9 0.05240 5 0.228 7 0.05221 _ t 0.228 5 N/A 2 t N/A 0.05222 2 t σ N/A 0.000127 Drop 3: d = 0.722m Drop 4: d = 0.981m Trial # t (sec) t 2 (sec 2 ) 1 0.382 2 0.1460 2 0.382 3 0.1462 3 0.382 2 0.1461 4 0.382 0.1464 Trial # t (sec) t 2 (sec 2 ) 1 0.312 9 0.09791 2 0.313 5 0.09828 3 0.313 1 0.09803 4 0.312 8 0.09784 5 0.312 1 0.09741 _ t 0.312 9 N/A 2 t N/A 0.09789 2 t σ N/A 0.00032

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
