Finding acceleration due to gravity lab2/21/2023 unless there was some kind of consistent error in the timing process such as being faster at pressing start than in pressing stop due to anticipating the end of the tenth swing. Of course your average over 30 swings should reduce your error by a factor of sqrt(30). Try increasing or decreasing your average time by that much and see how it affects the result. If you time something known to be very accurate, like a clock second had, you will probably find an error of something like 0.1 second. The expected results of this lab include: the acceleration due to gravity being 9.8m/s2, coefficient of kinetic friction being 0 due to the friction-less track, and the tension in the string being equal to the weight of the hanger. The stopwatch is very accurate, so your main error is going to be due to hitting the button at the wrong time. The acceleration of the hanger will then be measured using the Vernier motion detector. It would be interesting to try to estimate the accuracy of your time measurements and perhaps deduce from that the accuracy of the calculated value for g. That's why it is important to go to great lengths to measure the time accurately. Note that the time measurement is squared, so its error strongly affects the result. Experiment I: Acceleration of an Object in Free-Fall 1. Students often get 9.6 to 10 m/s² from this experiment because air resistance, etc. motion under the influence of constant acceleration and an appreciation for the varied ways of measuring the acceleration due to gravity and the errors inherent in these techniques. We investigate a variety of variables, including displacement, angle, damping, bob mass, and others. The simple pendulum experiment is used in this report to determine an approximate of 'g' (gravity). 1 to the length, you would have 8.9 instead of 8.0 for your answer. Acceleration due to gravity experiment using a pendulum lab report. Test case 2- 23.41s/10 =2.341 seconds per cycle. The purpose of this experiment is to determine the numerical value of acceleration due to gravity, and verify that it is independent of mass. Find the average time: Test case 1: 23.41s/10 =2.341 seconds per cycle. So i did make an attempt, can someone check if i am doing it right and if my answer seem fine for all questions. I don't know how to do average time, and if i get the average time wrong then i get number 2 wrong and then my answer for number 3 will be wrong. Using the period of the pendulum and its length, calculate the value of "g". Using this average time, calculate the period of the pendulum. Test case 3- time it took for the pendulum to complete 10 full cycles is 23.44 s. Test case 2- time it took for the pendulum to complete 10 full cycles is 23.41 s. Test case 1- time it took for the pendulum to complete 10 full cycles is 23.41 s. This lab is done assuming, there is no air resistance or any other force other than just gravity. We let it go from 20 degrees and counted 10 cycles and recorded how much time it took for the pendulum to complete 10 cycles. We did a lab using a pendulum attached to a string about 1.12m long.
