With a vernier caliper‚ measure the diameter of each cylinder to the nearest 0.01cm and record 3. Again‚ using the vernier caliper‚ measure the length of each cylinder to the nearest 0.01cm and record 4. Compute the volume of each cylinder by using the formula V= (3.14d2h)/4 For Zinc: 1.

9/16/14 Physics 01L Density Abstract This experiment was conducted in order to determine the density of the Aluminum metal samples provided in the lab. Specific tools such as the vernier caliper and balance scale were used to measure and record the values found. Given that density is a measurement of mass over volume‚ both of these quantities would have to be determined experimentally‚ prior to proceeding with the calculation of the density‚ for each of the

using vernier calipers. By finding the density‚ we could determine the specific gravity of the object(the ratio of its density versus that of water‚ ρwater=1000kg/m3). ρ=m/█(v@ ) Apparatus: Newton gauge‚ metal samples which are magnet bar‚ marble‚ pendulum bob‚ small nut and big nut‚ beaker‚ and graduated cylinder. Procedure: The weight of one of the metal samples is determined. The volume of the sample with a regular shape is determined by using direct measurement with the vernier calipers

Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then weighed on a gram slider and then recorded. The first data set was graphed mass (kg) against diameter^3

Equipment: * Metal Cylinder The dimensions of the metal bars had length of 101mm and diameter of 25mm. * Vernier Caliper Vernier Caliper is a measuring instrument. It is used to measure the diameter or lengths and widths of objects up to 100th of a mm. I used it for measure of the length and width of the metal bar. * Lathe Machine A lathe is a machine tool which
