Purpose: To find out if the weight of different objects effects the acceleration when falling. Materials and Procedure: See sheet Data: Data Table 1 Trial Time (s) # of dots Frequency (1/s) Period (s) 1 1.71 87 50.877 .019 2 1.74 90 51.724 .019 3 1.67 80 47.9 .021 4 1.32 82 62.12 .016 Average 1.61 84.75 53.15 .018 Data Table 2 Trial Mass (g) Time (s) Distance (m) Avg speed (m/s) 1 1000 ,594 .89 1.5 2 200 .432 .89 2.06 3 100 .468 .89 1.9 4 500 .45 .89 1.97 Calculations: Frequency = Number of dots / Time Period = Time / Number of dots Average speed = meters / seconds Questions: 1. What is the possible source of error in the measurement of the period …showed first 75 words of 342 total…

…showed last 75 words of 342 total…the lab we took 4 different weights to see if any would fall faster and just counted up the amount of dots and multiplied by .018 to see the time it took to fall. All of our weights when rounded to one significant digit took 2 seconds to fall meaning there is only a slight difference between them, which is caused by human error because they should have all taken the same exact time to hit the ground.
