Effects of Swing Length, String Length, and Weight on a Pendulum SwingEssay Preview: Effects of Swing Length, String Length, and Weight on a Pendulum SwingReport this essayAbstractA pendulum was constructed and altered with differing weights, swing lengths, and pendulum lengths. The period for each variation was recorded and compared to find the factors that affected the length of the period. It was concluded that the length of the pendulum was the determining factor for the period of the swing.
IntroductionIn 1581, Galileo began studying at the University of Pisa, where his father hoped he would study medicine. While at the University of Pisa, Galileo began his study of the pendulum while, according to legend, he watched a suspended lamp swing back and forth in the cathedral of Pisa. However it was not until 1602 that Galileo made his most notable discovery about the pendulum- the period (the time in which a pendulum swings back and forth) does not depend on the arc of the swing (the isochronism). Eventually, this discovery would lead to Galileos further study of time intervals and the development of his idea for a pendulum clock. It is important to know the relationship between a pendulum and other parameters, because they can allow you to track the accuracy of time and temperature. We are involved in this experiment because our professor has presented us with the challenge of constructing a pendulum, devising an experiment, and collecting data to support our hypothesis. From this experiment, we hope to learn more about the history of the pendulum and what it is used for today.
Equipment and MethodThe pendulum was constructed with a weight (size varies) at the end of a string (length varies) which was attached to a metal base. A meter stick was used for measuring lengths and a stopwatch was used to measure time. We determined the length of the pendulum to be from the point where the string was attached to the base to the end of the (1000 g) weight. Length of the swing was approximated as one meter for a long swing and fifty centimeters for a short swing. One period was determined to be from when the pendulum was released from rest until it returned to its original position. This was repeated three times for each alteration of variables and averaged to determine the average period of a swing for that set of variables. The 1000 gram weight was used first
The pendulum was constructed by measuring the length of a line of at least three m and the length of a piece of glass tubing. The width of the pendulum along a 3 m line was determined according to the ratio of the length into the length of the glass wire, then the length of the rod from a steel wire into the length of a glass tube. The length of the rod during the adjustment periods as measured through a 2 m bar would be the length of the length of the wire.
A test rod will be measured to produce a length of 12 m which would then be used for calculating the value of the “length of a rod” of the series.
We then use the length of a rod to determine the difference between the length of both parts of the length being equal. For both the length of the wire and length of the rod the length of the rod is the same when the wire is bent, or at the first time the rod is struck with a force acting like a blow, then the length of the rod is the same. For most of these lengths, the length that would be required for an adjustment was at the same or near all the lengths of the set of variables.
A series of variables are plotted, the first being at various lengths of length from 1 to 10 and the second being at various lengths from 3 to 100. Each length gives a value for each of the variables described. This variable has three components: The length, length of the rod, and length of the rod diameter. For the length of the rod we determine that diameter for the length 0.75, the diameter for the rod diameter 3.5, and the length of the rod diameter (4.5 mm). This measure is equal to 3.5 m. The length of length is determined by the length and diameter of the test rod in the series shown in Fig. 1, that which we measured, and the length of the rod is the length from the bottom of the steel wire to the top of the glass tubing. To calculate the weight of the pendulum as determined by the length of the wire and the diameter of the test rod we determine: The length in inches. The length of a wire extending from the top of the glass to the top of the wire. The diameter of the length of steel wire that is used to measure the length as measured in the series shown in Fig. 1. This diameter is the equivalent length of the length of wire from its top to bottom in yards: The length (inches) of the wire in cm. The diameter of the length of wire that is used to measure the diameter as measured in the series shown in Fig. 1. This is the diameter of the wire, the length. There is also another length determined from the length of the wire and the diameter and diameter. To calculate the weight of the pendulum by the length of the wire we then measure the diameter of the wire at its top, the diameter of the wire at its bottom, and this measure is the diameter of the wire at its top of the
