force table experiment sources of error Pigeon, Michigan

This is very important because, if this angle is off, all of the other angles in the experiment would be different and it would change the entire experiment. What types of errors (experimental and/or random) can occur during a force table lab, and why? Fig. 1. For example, the following table keeps track of the numbers of exercise 1.

Physics Question? We did an experiment on the force table (pic of a force table below) and my question is to note the major sources of error that come with an experiment involving Trending Now Purdue University Kaley Cuoco Whitney Houston Corey Feldman Airline Tickets iPhone 7 Kim Zolciak Justin Timberlake Nick Kyrgios Auto Insurance Quotes Answers Relevance Rating Newest Oldest Best Answer: If Louis, MOSaturn V Launch Vehicle Flight Evaluation Report - As-503 Apollo 8 MissionEvolution of the Solar SystemApollo Navigation Ground and Onboard Capabilitiestmp91E7.tmptmp4567.tmpApollo 12 Mission ReportApollo 15 Mission ReportSkylab Experiments.

The "best" value of this force is at the center of this range. The system returned: (22) Invalid argument The remote host or network may be down. This is important because it throws off the real numbers for equilibrium. Its head is at coordinate (16.2,4.7) and its tail is at (6.5,9.8).

Using a ruler and a protractor, construct vectors whose scaled length and direction represent F1 and F2. The discrepancies between the graphical, experimental, and analytical results are relatively minimal, the largest discrepancy existing between the calculations from the analytical and graphical analysis. Its x component is therefore 16.2 - 6.5 = 9.7, and its y component is 4.7 - 9.8 = -5.1. Components of vectors by the analytic method.

Rank the relative importance of these errors in your data.I think that the most important factor in this list would be the errors in direction of the forces if the strings If there was an error in the angles of the strings that would upset the resultant force reguired to keep the ring stable. In each situation, adjust the weights and angles so that the ring is centered on the table, and is not touching the center post.

Record the uncertainty of the force and its percent uncertainty. Why is this important? Use enough weight on the hangers so the strings are nearly parallel to the table and do not sag much. Without this uniformity, the whole experiment would have turned up different numbers due to error. Create a free website Powered by Create your own free website Start your own free website

Lay an edge of the triangle along the vector, then lay a ruler along another edge of the triangle. You can only upload files of type PNG, JPG, or JPEG. Carry out this analysis for both experimental situations. (2) ANALYTIC METHOD. The lab involves the demonstration of the process of the addition of several vectors to form a resultant vector.

The center post keeps the ring centered while the system is being balanced.

Conclusion: In conclusion, the vector force table was used to experimentally demonstrate vectors “in action”. Another source of error could be that the pulley on the vector force table is not horizontal, which could also end up a²ecting the equilibrium.

Also, human error could have caused us to misread or misuse our instruments. Calculate the magnitude of the forces produced by these masses and record them in Table 1. This preview shows document page 3. You can only upload videos smaller than 600MB.

Record the amount of weight on each hanger, and read the direction of its string on the table's scale. Three forces are applied to strings attached to a small round metal ring around a center post. Take care to adjust the pulleys so the strings pass straight over them, ensuring minimum friction. The force table apparatus demonstrates the addition of forces acting on a body, in two dimensions.

Investigate and record the error in the angle in the same way. 7. The vector sum of the forces on a body is important because it determines whether the body will move, and how it will move. Ask a homework question - tutors are online ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: Connection to Errors would increase as there would be more friction without the pulleys as the strings would catch on the end of the force table; results would be skewed.

ANALYSIS: Fig. 2. hope it helps. APPARATUS: Force table, three weight hangers, metric weight set, 17 x 11 or 17 x 22" drawing paper. 3. For each situation, choose arbitrary X and Y axes, and resolve the vectors into components along these axes.

QUESTIONS: (1) If the weights of the weight hangers were exactly the same could their weights have been neglected in the computations? Whether one chooses to use a ruler and protractor or a computer program there is a potential for error. Follow 3 answers 3 Report Abuse Are you sure you want to delete this answer? This "convenience unit" is sometimes called the "gram-weight." 5.

The vector is pointing "downward" (negative) with respect to the y axis, but "forward" (positive) with respect to the x axis. Without pulleys, it may have been much more difficult to set up the correct angles and to make the conditions of each string and weights identical. Is its size consistent with the error caused by error in each of the individual forces? On a clear area of your work sheet, transfer the forces onto a vector polygon and test whether the polygon closes.
