Measurement Lab
Title: Measurement Lab
Date: September 4, 2014
Partner: Abbey Applegate
Purpose
The purpose of this lab experiment is to utilize multiple tools to collect data. The dimensions of an object will be measured with a ruler, a vernier caliper, and a micrometer. The mass of an object will be measured with an electronic balance, a force sensor, and a spring scale. The length of the period of the object suspended in a pendulum will be measured using a handheld stopwatch, frame-by-frame count of a video, and a photogate. Special consideration will be given to accuracy, precision, and uncertainty.

Length
The length of the cylinder was measured with a ruler to be 6.27 ± 0.01 cm.
Using a vernier caliper, the length of the cylinder was measured to be 6.370 ± 0.005 cm.
The length of the cylinder exceeded the measurement capabilities of the micrometer. No measurement was taken for this tool.

Diameter
The diameter of the cylinder was measured with a ruler to be 2.29 ± 0.01 cm.
With a vernier caliper, the diameter of the cylinder was measured to be 2.000 ± 0.005 cm.
Using a micrometer, the diameter of the cylinder was measured to be 22.82 ± 0.01 mm, which was converted to 2.282 ± 0.001 cm.
With a vernier caliper, the diameter of the cylinder was measured to be 2.000 ± 0.005 cm.
Using a micrometer, the diameter of the cylinder was measured to be 22.82 ± 0.01 mm, which was converted to 2.282 ± 0.001 cm.
Mass
With an electronic balance, the mass of the cylinder was measured to be 23.5 ± 0.1 g.
The mass of the cylinder was measured with a force sensor to be 23 ± 3 g, after being converted from the initial measurement of 0.23 N.
Using a spring scale, the mass of the cylinder was measured with a spring scale to be 25 ± 1 g.
The mass of the cylinder was measured with a force sensor to be 23 ± 3 g, after being converted from the initial measurement of 0.23 N.
Using a spring scale, the mass of the cylinder was measured with a spring scale to be 25 ± 1 g.
Time
The length of ten periods of the object on a pendulum was measured with a stopwatch to be 17.15 ± 0.01 s. This number was then divided by ten to determine the length of one period at 1.715 ± 0.001 s.
The video below was used to find the length of the period of the object on the same pendulum. A frame-by-frame analysis of the video was used to determine that the length was 51 frames. With a conversion factor of 30 frames per second, the measurement was calculated to be 1.7 ± 0.1 s.
Using a photogate and accompanying Data Studio software, the length of the period was measured to be 1.697 ± 0.001 s.
