Akshay Patel 09/11/08 Physics Lab Period 10 Gathering and Analyzing Data Conclusion: There is a relationship between the circumference and the diameter when measuring circular objects. To get from the diameter to the circumference, you must multiply the diameter by pi, or 3.14. But when measuring hands on with a string, there is much room for error. Especially with the ruler, you aren’t able to make a real precise measurement. The most you can get down to is the tenth place when measuring with a ruler. For example when measuring the bouncy ball, we got a diameter of 5.2 cm and circumference of 17.1 cm. Then, we

Unformatted text preview: did actual calculations with by and multiplied 5.2 with pi and divided the circumference with 17.1. This is where we see the room of error. Also, we saw the difference value of pi when we divided 17.1 by 5.2. Pi became the value 3.3. So the reasons of error would most likely be the ruler not being as precise by going down only to the tenths place. Also, the person who measured can always make a mistake. More precise and correct measurements couldve been made with a ruler that was more precise, or a better way of measuring....
