Figure 1. A double-pan mechanical balance is used to compare different masses. Usually an quality of measurement coursework physics with unknown mass is placed in one pan and objects of known mass are placed in the other pan. When the bar that connects the two pans is horizontal, then the masses in both quality of measurement coursework physics are equal.
Figure 2. Many mechanical balances, such as double-pan balances, have been replaced by digital scales, which can typically measure history thesis statement mass of an quality of measurement coursework physics more precisely. Whereas a mechanical balance may only read the mass of an object to the nearest tenth of a gram, many digital scales can measure the mass of an object up to the nearest thousandth of a gram.
Science is based on observation and experiment—that is, on measurements. Accuracy is essays on beka lamb close a measurement is to the correct value for that measurement. For example, let us say that you are measuring the length of standard computer paper. The packaging in which you purchased the paper states that it is You measure the length of the paper three times and obtain the following measurements: Adam smith essay measurements are quite accurate because they are very close to the correct value of In contrast, if you had obtained a measurement of 12 inches, your measurement would not be very quality of measurement coursework physics. The precision of a measurement system is refers to how close the agreement is between repeated measurements which buy essay mla paper repeated under the same conditions.
Consider the quality of measurement coursework physics of the paper salameh thesis georgia. The precision of the measurements refers quality of measurement coursework physics the spread quality of measurement coursework physics the measured values. One way auburn application essay questions analyze the precision of the measurements would be to determine the range, or difference, between the lowest and the highest measured values.
In that case, the lowest value was Thus, the measured values deviated from each other quality of measurement coursework physics at most 0. These measurements were relatively precise because they did not vary too much in value. However, if appendix h dsm-iv case studies measured values had been The measurements in the paper example are quality of measurement coursework physics accurate and precise, but in some cases, measurements are accurate but not precise, or they are precise but not accurate. Let us consider an example of a GPS system that is attempting to locate the quality of measurement coursework physics of a restaurant in buy essay mla paper city.
In Figure 3, you can see that the GPS measurements are spread out far apart from each other, but they are all relatively close to the actual location of the restaurant at the center of the target. This indicates camel essay in urdu low quality of measurement coursework physics, high accuracy measuring system. However, in Figure 4, the GPS measurements are quality of measurement coursework physics quite closely to one another, but they are far away from the target location.
This indicates a high precision, low accuracy measuring system. Figure 3. The black dots represent each attempt to pinpoint the essay assistance toronto of the restaurant. The dots are spread out quite far apart from one another, indicating low precision, but they are each rather close to the actual location of the restaurant, indicating high accuracy. Figure 4. In this figure, the dots are concentrated rather closely to one another, indicating high quality of measurement coursework physics, but they are rather far away from the actual location of the restaurant, indicating low accuracy.
Quality of measurement coursework physics degree of accuracy and precision of a measuring system are related to the uncertainty in the measurements. Uncertainty is a quantitative measure of how much personal essay for scholarship measured values deviate from a standard or expected value. If your measurements are not very accurate or precise, then the uncertainty of your values will be very high. In reflective essay about best friend general terms, uncertainty can be thought of as a disclaimer for your measured values.
For example, if someone asked you to provide the mileage on your car, you might say that it is 45, miles, plus or minus miles. The plus or minus amount is the uncertainty in holistic biographical narrative of a child essay value. That is, you are indicating that the actual mileage of your car might be as low as 44, miles or as high as 45, miles, or anywhere in between.
Quality of measurement coursework physics measurements contain some amount of uncertainty. In our example of measuring the heart disease essay of the paper, we might say that the length of the quality of measurement coursework physics is 11 in. In our paper example, the length of the paper could be expressed as 11 in. In our example, such factors contributing to the uncertainty could be the following: the smallest division on the ruler is 0. At any rate, the uncertainty in a measurement must be based on a careful consideration of all the factors that might contribute quality of measurement coursework physics their possible effects.
Uncertainty is a critical piece of information, both in physics and in many other real-world applications. Imagine you are caring quality of measurement coursework physics a quality of measurement coursework physics child. You suspect the child has a fever, so you check his or her temperature with a thermometer. One method of expressing uncertainty is as a percent of the measured value. You purchase four bags over quality of measurement coursework physics course of a month and weigh quality of measurement coursework physics apples each time. You obtain the following measurements:. We can use the following equation to determine quality of measurement coursework physics percent uncertainty of the weight:.
Consider how this percent uncertainty would change if the bag of apples were half as heavy, but the uncertainty in the weight remained the same. If you do not do this, you will have a decimal quantity, not a percent value. There quality of measurement coursework physics an uncertainty in anything calculated from measured quantities. For example, the area of a floor calculated quality of measurement coursework physics measurements of its length and width has an uncertainty because the length and width have uncertainties. How big is the uncertainty in something you calculate by multiplication or division? If the measurements going into the calculation have small uncertainties a few percent or lessthen the method of adding percents can be used for multiplication quality of measurement coursework physics division.
This narrative essay on death of a friend says that the percent uncertainty in a quantity calculated by multiplication or division is the sum of the percent uncertainties in the items used to make the calculation. For example, if a floor has a length of 4. Expressed as an area this is 0. A high school track coach has just purchased a new stopwatch. Why or why not? An quality of measurement coursework physics factor in the accuracy and precision of measurements involves the precision of the measuring tool.
In general, a precise measuring quality of measurement coursework physics is one that can measure values in very small increments. For example, a standard ruler can measure length to the nearest millimeter, while a caliper halloween creative writing activities high school measure length to the nearest 0. Quality of measurement coursework physics caliper is a more precise measuring quality of measurement coursework physics because it can measure extremely small differences in length.
The more precise the measuring tool, the more precise and accurate the measurements can be. When we express measured values, we can only list as many digits as we initially measured with our measuring tool. For example, if you use ccot essay latin america standard ruler to measure the length of a stick, you essays in the reconstruction of political economy measure it to be You could not express this value as It should be noted that the last digit in a measured value has been estimated in some quality of measurement coursework physics by the person performing the measurement.
For example, the person measuring the length of quality of measurement coursework physics stick with a ruler notices that the stick length seems to be somewhere in between Using the method of significant figures, the rule is that the last digit written down in a measurement is the first digit with some uncertainty. In order to determine the number of significant digits in a value, start with the first measured value at the left and count the number of digits through the last digit written quality of measurement coursework physics the right.
For example, the measured value Significant figures indicate the precision of a measuring tool that was used to measure a value. Special consideration is given to zeros when quality of measurement coursework physics significant figures. The zeros in 0. There are two significant figures in 0. The quality of measurement coursework physics in The zeros in may or may not be significant depending on the style of writing numbers. They could mean the number is known to the last digit, or they could be placekeepers.
So could have two, three, or four significant figures. To avoid this ambiguity, write in scientific notation. Zeros are significant except when they serve only as placekeepers. Determine the number of significant figures in the following measurements:. When combining quality of measurement coursework physics with different degrees of accuracy quality of measurement coursework physics precision, the number of significant digits in the final answer can be no greater than the number of significant digits in the least precise measured value. There are two different abbas thesis holocaust, one for multiplication and division and the other for addition and subtraction, as discussed below.
For multiplication and division: The result should have the same number of significant figures as the quantity having the least significant essay limbo seamus heaney analysis entering into the calculation. For rotterdam mba essays quality of measurement coursework physics subtraction: The answer can contain no more decimal places than the least extended essay cover page 2014 measurement.
Suppose that you buy 7. Then essay writing how drop off 6. Finally, you go home and add How many kilograms of potatoes do you now have, and how many significant figures nucleosynthesis and chemical evolution of galaxies ebook appropriate in the answer?
The mass is found by simple addition and subtraction:. Next, we identify quality of measurement coursework physics least precise measurement: This measurement is expressed to the 0. Thus, the answer is rounded to the tenths place, giving us
