Lab 2 is a quantitative lab. To be successful in lab 2, you will need to first learn about experimental uncertainties. To help you learn about them there is a document that will be provided. Please read the document carefully. After you finish reading, solve the following problems. They will help you learn how to estimate uncertainties and how to use them to evaluate experimental results. Please complete the homework at home on a separate sheet of paper before coming to lab 2. The following instruments are available in your laboratory. What would be the absolute uncertainties in the measurements made with these instruments? Measure the length of the pencil. Estimate the relative uncertainty in the measurement.

Solution

1.a. 1mm

b. 1/2 degree

c. 1 second

d. 1 gram

2. Relative uncertainity = 1mm/73mm =1/73
