Physics Lab

II. Objective:

The objective of this lab is to learn how to use additional statistical methods in order to convert inches to centimeters. Students were able to compare different instruments' accuracy such as, vernier caliper and the micrometer caliper, to gather data to determine which instruments gave more accurate readings. 

III. Theory:

The number of significant figures is important when calculating measuring for precise readings. When taking precise measurements, the most ideal devices are the ones at which gives the most significant figures. The logic behind it is the more numbers the instrument gives the better its accuracy. Instruments that that provide readings to the nearest 10th, such as an inexpensive ruler, will give less accurate readings compared to a micrometer that give reading to the nearest 1000th. In short, the precision of the measurement depends on the instrument ability to provide measurements with the most significant figure.

Method of investigation: Procedure 1)

1. Examined the English and Metric sides of an inexpensive ruler and meter stick.

2. Examined the measurements of the vernier and micrometer calipers.

3. Found the zero correction for the Vernier caliper.

4. Repeated the zero correction for the micrometer.

5. Used the inexpensive ruler to measure the length, width, and height for a block. Repeated this step four times at different points on the block.

6. Used the data to calculate an average.

7. Used the vernier caliper to measure the length, width, and height for a block. Repeated this step four times at different points on the block.

8. Used the data to calculate an average.

9. Used the vernier caliper to measure the inside dimensions of a cylinder cup. Repeated this step four times at different points of the cylinder cup.

10. Used the data to calculate an average.

11. Used the micrometer caliper to measure the diameter of a sphere. Repeated this step four times at...
