ObjectivesThe goal of this lab was to use a ruler to get accurate lengths of height, length, and widthof a bar and the height and diameter of three cylinders. We also wanted to calculate the volumeand density based on these values (and by calculating the mass using a beam balance) as well ascalculate the displacement by testing in a graduated cylinder.Physical PrinciplesAn objects mass is a measure of how much matter it is regardless of any forces acting onit. An objects mass can be measured through a balance scale. An objects height is the longestmeasurement of side to side. The width is the shorter of the two measurements from side to side.An objects height is its measurement from bottom to top. A ruler is a measuring tool. Height,length, and width are all considered dimensions. These dimensions can be multiplied to find thevolume in a formula: V= LxWxH, in which L is the length, W is the width, and H is the height.Volume is the amount of space an object occupies. This formula applies to objects like a bar orblock. For the volume of a regular cylinder the formula is: V= (πd2H)/ 4, in which d is thediameter. The diameter is the measurement straight through a circle or the center of a sphere. Thediameter is also considered a dimension and can be measured using a ruler. Displacement isanother way to measure volume based on the displacement of water, occupying the volume thewater would have taken up. Displacement is measured as subtracting the final volume of water inmL in a graduated cylinder, after placing the cylinder in it, from the initial volume of water inmL in a graduated cylinder, from before placing the cylinder in it, in the formula:v= v1-v0.Density is a quantity that relates an objects mass to its volume as a degree of acompactness of that object. Density, across all cylinders, oddly shaped objects, and bars, ismeasured by the formula: density=p= M/V. The % difference in density

Then, by using the ruler, we measured the height,length, and width of the aluminum bar to the nearest thousandths of a cm in order to find thedimension volume. After, we measured the height and diameter of the [aluminum] cylinder, the[copper] cylinder to the nearest hundredths of a centimeter or thousandths of a centimeter,whichever we measured to be precise in order to find the dimension volume.
