310 Physics Experiment 1 Measurement Laboratory DATA SHEET Name: ___________ Date: ____5/2/2011____ 1. What is the precision of the vernier caliper? - 0.01mm 2. Record your measurements of the diameter of the quarter in the table below. diameter (d) measurement #1 measurement #2 measurement #3 measurement #4 measurement #5 average 24.18 24.23 24.06 24.24 24.20 24.18 radius (r) 12.09 12.12 12.03 12.12 12.10 12.09 3.

What coin did you choose for the next part of the experiment? - Nickel 5. Record your measurements of the diameter of the coin in the table below. diameter (d) measurement #1 measurement #2 measurement #3 measurement #4 measurement #5 average 21.12 21.10 20.86 21.12 21.14 21.10 radius (r) 10.56 10.55 10.43 10.56 10.57 10.53 6.

Why is it a good idea to average your measurements? - It is good to get a multiple samples to get the most accurate readings as possible. If you take just one sample your results may not be accurate enough to present. 8. What is the accuracy of your diameter measurements? - 0.01mm Phys310 Lab Page 1 Physics 2 Experiment 310 Experiment 1 Measurement Laboratory continued 9. What is the accuracy of your thickness measurements? - 0.01mm 10. Use the averages of your measurements and the coin masses listed in the table in the introduction and calculate the volume and density for the quarter and your coin. Record your results in the table below. Be sure to use the appropriate number of significant digits and units. Volume Quarter 776.05mm^3 Other coin 644.43mm^3 Density 0.0090g/mm^3 0.0012g/mm^3 11. Is the coin you chose made of the same metal as the quarter? How do you know? - Yes, according to their density they should be from the same type of metal (alloy). 12. How many quarters would be required to make a stack as tall as your height? - I would need about 1172.31 quarters to equal 65. 13. What would the total mass of such a stack be? - 6564.94g 14. Could you use your caliper to measure the thickness of a sheet of paper? To what accuracy? To what precision? - Yes, to .01mm. 15. Devise a scheme to measure the average thickness of the pages of a book more accurately than using the caliper on a single sheet. Describe and implement your scheme. - If a caliper can measure to an accuracy of .01mm then you can multiply the thickness of a single sheet of paper by the number of pages. Then measure the thickness of the covers and add that to your result. - 0.06mm - 0.35mm - 0.42mm Single piece of paper Front Cover Back Cover Math: 0.06*70(sheets) + 0.35(F.Cover) + 0.42(B. Cover) = 4.97mm Phys310 Lab Page 3 Experiment 1
