Our First Lab:Analizing the Motion of a Pendulum

In Fridays class we went over the work sheet we had done in the previous class, correcting an elements of physics work sheet. That was filled with fill in the blank and true and false questions, based on a video we had watched.


Then we got a hand out with the list of labs we would be doning in Physics 20. We also learned how to properly write out the labs by titling the title, problem, materials, proccedure, data and observatoin, and ending off with a conclusion.


We started our first lab, Analizing the motion of a Pedulum. During this procedure we used an apparatus, stopwatch, protractor, and various size's of weights. In this lab we had to determine the lenght of time in seconds, it is required to take in 10 cycles. You would then start with the length of string at 100cm, and then decrease the length by 20cm each time at a 20 degree angle. This will help determine the frequency of the pendulum for each length. Then you are asked to create a chart and answer the following questions of What happens to the frequency of a pendulum as its length increase? What happens to the period of a pendulum as its length increase?

Then you had to repeat one of the previous procedures, by useing the identical length in the first observation, but change the degree of 20 to an angle of 10 degrees. Then record the frequency and compare.


The next step is to repeat one of the procedures you have already done, with a smaller size of weight, and compare the frequencys that you have already obtained by the previous recorded data. Be sure sure to use the 20 degrees and not the 10 degree angle, then record and compare.


We ended off the class by putting away all of our materials we used, and im pretty sure we will be given more class time to work on this lab on monday.


The next person to write for the blog is Summer Harris. :)
