Question Description

Hi

I need help with my physics report and the assignment is about 4 part please read the documents carefully before you start working on it.


Thank you!


Part 1: Types of Errors Pick whether the below scenario is random or systematic 1. Measuring the length of an object using a caliper to the nearest hundredth of a millimeter. Random ☐ Systematic ☐ 2. Mis-calibrated current sourcemeter. Random ☐ Systematic ☐ 3. An effect that was not thought of during the collection data, but it biased the results. Random ☐ Systematic ☐ 4. You make a bunch of measurements of the gravitational acceleration constant (close to Earth’s surface). The results are measured in meters/second/second (m/s2). Below are your results: 11.3, 12.0, 11.1, 10.9, 11.0, 11.5, 11.1, 11.3, 10.9, 11.0, 11.7, 11.2, 11.1, 11.8, 11.5, 10.9, 11.1, and 11.7 Referring to the data collected, using just a measured distance and photodetector to measure the time interval of the falling object. What type of error would you think is present? Random ☐ Systematic ☐ Part 2: Accuracy and Precision 1. Select the best description for the scenarios below: ACCURACY: ☐ ☐ ☐ ☐ PRECISION: ☐ ☐ ☐ ☐ 2. Using the information and data from question 4 in Part 1, discuss the accuracy and precision of the data set. Download the Error and analysis worksheet (Part 3 and 4) and complete it before leaving the lab!!! Save this Worksheet as a PDF Submit both Worksheets to canvas

Part 1: Types of Errors
Pick whether the below scenario is random or systematic
1. Measuring the length of an object using a caliper to the
nearest hundredth of a millimeter.
Random
2. Mis-calibrated current sourcemeter.
Systematic
3. An effect that was not thought of during the collection data,

but it biased the results.
Random
4. You make a bunch of measurements of the gravitational
acceleration constant (close to Earth’s surface). The results
are measured in meters/second/second (m/s2). Below are
your results:
11.3, 12.0, 11.1, 10.9, 11.0, 11.5, 11.1, 11.3, 10.9, 11.0,
11.7, 11.2, 11.1, 11.8, 11.5, 10.9, 11.1, and 11.7

Referring to the data collected, using just a measured
distance and photodetector to measure the time interval of
the falling object. What type of error would you think is
present?
Systematic
Part 2: Accuracy and Precision
1. Select the best description for the scenarios below:

Precision

None

Accuracy and

Accuracy
