Sources Of Error In A Simple Pendulum Experiment
The spring constant calculated from this graph was 25.6 Nm-1 which is comparable to the 28.0 Nm-1 from the first experiment. The reason why you measure for so many points is to get some redundancy and statistics. Are your results any better when using the more accurate relationship m+1/3m (where m is the hanging mass and mx is the mass of the spring)? Random Errors Random errors are positive and negative fluctuations that cause about one-half of the measurements to be too high and one-half to be too low. navigate here

Sources Of Error In A Simple Pendulum Experiment
Everyone who loves science is here! Would it be more for the paper-clips or pendulum? First, we used a spring upon which we added masses and then measured the distance the spring stretched with a ruler. From here, we ran several different tests during which we changed different variables.
Ideally, they should increase in a linear fashion and their frequency should equal the frequency for the first harmonic times the number of harmonics. 5. Which are relevant at all?

It disturbs the measurement of counting the oscillation. Simple Pendulum Lab Conclusion You can only upload files of type 3GP, 3GPP, MP4, MOV, AVI, MPG, MPEG, or RM. Environmental. Calculate the tension T that would be required to produce the n = 1 standing wave for the red braided string. 2.
- Please upload a file larger than 100x100 pixels We are experiencing some problems, please try again.
- Random errors, unlike systematic errors, can often be quantified by statistical analysis, therefore, the effects of random errors on the quantity or physical law under investigation can often be determined.
- But I'm sure they all would involve mistakes in measurments or counting.
Systematic Error In Pendulum Experiment
What is the effect of changing frequency on the number of nodes? This demonstrates that relatively accurate calculations were obtained from our methods, proving that the spring force constant COULD be accurately determined from the way we performed the experiment. Sources Of Error In A Simple Pendulum Experiment Then, we hung several weights from the end of the string that made its way over the pulley. Simple Harmonic Motion Lab Sources Of Error help!

There was evidence that the spring force constant was indeed constant for each method. Standing waves can be observed in the real world and not just in an experimental situation. What Are The Sources Of Error When Performing The Single Pendulum Experiment
How about air resistance? Let's say you have an awesome stopwatch. You can only upload videos smaller than 600MB. http://nzbsites.com/sources-of/sources-of-error-in-chemistry-lab-experiment.html Raul Lai, Feb 9, 2011 Feb 9, 2011 #10 betel Well if your classmates use the same data there is no wonder they get the same result as you do.
For a usual simple pendulum I do not see where your external force should come into play. Precautions For Simple Pendulum Experiment For information on the Digital Object Identifier Handle, please visit the website of the DOI Foundation, at www.doi.org. Then you can try to find reasons for why you are getting an offset.
Apparatus 0.100kg masses - The 7 100g masses I am planning to use in my experiment actually have an average mass of 0.098kg meaning there is a percentage error of around
The answers you posted in your original post obviously come from some other similar experiment and you copied them before thinking if they are relevant. It can be very difficult to get a correct and precise measurement when the time for the period is so small. Table of Contents Period of a Mass on a Spring Lab Standing Waves Lab Amanda, Michael, Ben, Kaila Objectives: To directly determine the spring constant k of a spring by measuring Simple Harmonic Motion Error Analysis First, we kept the hanging mass and the linear density of the string constant and changed the harmonic number, frequency, wavelength, and wave speed to determine the relationship between frequency and
You can only upload a photo (png, jpg, jpeg) or a video (3gp, 3gpp, mp4, mov, avi, mpg, mpeg, rm). The driving frequency of the external force should be closer to the natural frequency of the system and the angle between the bob and vertical should be small in order to Do you think baby paper clips are the work of the devil? http://nzbsites.com/sources-of/sources-of-error-in-static-friction-experiment.html While it was not much and most likely did not have a significant impact, the slant could have changed some data in very tiny amounts.

Video should be smaller than 600mb/5 minutes Photo should be smaller than 5mb Video should be smaller than 600mb/5 minutesPhoto should be smaller than 5mb Related Questions Errors in a pendulum Results Mass (kg) Extension (m) 0.100 0.04 0.200 0.07 0.300 0.10 0.400 0.13 0.500 0.17 0.600 0.21 This gives a value of 28.0 Nm-1 for the spring constant of the spring
We then compared the two values to prove whether or not they were identical. I also need 5 human errors! The result in my experiment didn't. How about air resistance?
The percentage error in this measurement will be about 3.3% which is quite large but if the amplitude was changed so as to give a percentage error of 1% or below source of error 1. Think of someone putting a wedge into the pivot point, that would push the pendulum backwards or forwards depending on how you did it, and the pendulum could not swing freely The error in your experiment should come mainly from what you measure...
If the relationship between frequency and harmonic number is found, then it will be found to be a linear relationship. We would then however encounter problems with friction between the plastic tube and the masses. Atheists, do you think the conclusion of the 'Schrodinger's Cat' thought experiment violates the law of noncontradiction? 20 answers The Pendulum? 7 answers Why do sound waves travel at a speed
