Physics Measurement of Length

1014 words 5 pages

Physics is the scientific study of matter and energy and how they interact with each other. Physics utilizes the scientific formula to test hypothesis and calculate matter such as density. Tools were created to measure material in a laboratory and have been perfected to reduce error. In this experiment measurement of length, mass, volume and density will be obtained through instruments of measuring and calculations. The objects being measured will be two cylinders, one brass the other iron and a glass ball. There will be two sets of table requiring data obtained from the objects including height, diameter, volume, mass and density.

5. Use a clean micrometer caliper to determine the zero reading. The screw will be brought close to contact with the anvil by turning the thimble directly. Turn the ratchet slowly until it clicks several times. If the ratchet is not present merely let the screw approach the anvil very slowly and stop as soon as both surfaces touch. Record the value of the reading in centimeters and read to 0.0001 cm, estimating to one tenth of the smallest scale division. Make four independent determinations of zero readings. 6. Next measure the diameter of the cooper wire with the micrometer caliper. The measurement is made by placing the wire between the screw end and the anvil. Use the ractchet and if there is none, care should be taken. Record the reading in centimeters and read to 0.0001 cm estimating to one tenth of the smallest scale division. Make six independent measurements of the diameter of the wire. 7. Determine the mass of each cylinder of the solid and of the wire using the triple beam balance.
