Graphical analysis of motion experiment2/18/2024 ![]() This experiment is divided into four activities namely, Graphical Analysis of Human Motion, Graph Matching, Graphical Analysis of Motion, and Reaction Time. Alcantara,Ĭollege of Science, University of Santo Tomas Print out a copy of the graph (under “file” choose “page setup” and click on “landscape,” then under “file” choose “print graph”).Mary Joyce M. You can change the upper and lower limits on the axes by clicking on their values in the graph. Make sure the limits of your graph include the origin (0,0). ![]() Graphing Open the “freefall” file and enter your t, y data in the designated columns. Just pick a dot near the start of the tape so that the missing or questionable dot is one of the dots skipped over in counting out every third dot for measurement. (*) If you have one or two dots missing on a tape it is usually not a problem. Record in your table the t and y values for every third dot. ![]() Chances are the mass was moving before the first spark actually hit the paper.) Since the dots are produced every 1/60 of a second, the time interval between every third dot is 3/60 s =. (Note: Just because we set y0 = 0 at t = 0 doesn’t mean the initial velocity is zero. Make sure that the meter stick does not move from this point on until the table on your worksheet is completed. Line up a convenient spot on the meter stick with one of the first dots. The meter stick should be placed on its narrow edge so the rulings extend to the tape for easy accurate measurement. To analyze the motion you will need to find the positions of all of the dots using a meter stick. If you find this is true with your tape, read the (*) below. Occasionally a spark fails to form at the proper time and a dot will be missing. You should see that they continually get further apart due to the acceleration of the mass as it falls. Recording data from waxed tape Obtain a wax tape from your TA and tape it flat to the table for measurement. El Electromagnet Mass Sparks jump to metal post melting dots on waxed tape that is against the post. As the mass falls sparks are generated every 1/60 of a second and these sparks are recorded on waxed tape that is in place vertically next to the mass. To record the position of the mass as it falls, a spark timer is used. When the current is turned off to the electromagnet, the mass falls to the ground. The instructor will use a free-fall apparatus that has a mass held in place by an electromagnet. If we set yo = 0 at t = 0 our equation simplifies to: y = vot + ½ gt2 Equipment For this experiment the lab instructor will operate the equipment. ![]() One of the equations of motion that we can use to help understand free-fall is: Δy = vot + ½ at2 For this lab it is convenient to choose downward as positive. Knowing what the general shapes represent and knowing what the slopes of the graphs represent will make the lab much more understandable. time graphs for objects that are in free-fall. Lab Preparation To prepare for this lab you will want to review position vs. Download Lab 2 -Graphical analysis of free-fall motion and more Summaries Experimental Physics in PDF only on Docsity! Graphical Analysis of Free-fall Motion Goal: To find the acceleration of an object in free-fall by using graphical techniques.
