Lab Report :: essays research papers

Hypothesis I tin can successfully institute vectors.Introduction A vector is a meter that has magnitude (speed, force, and/or length) and direction. For example, if a person is traveling East at 60 mph, accordingly s/he is traveling in the direction East and at a magnitude of 60 mph. A scalar is a quantity with only a magnitude. Common scalars include currency, mass, time, and acceleration. It wouldnt make aesthesis to say the sweater costs $38.00 southwest, so we leave off the direction. The magnitude symbol ( ), an arrow, can express direction by its careen on a coordinate plane and its length, which is usually offered. In this lab, I as well as use the directional measurement unit of Azimuth (Az), which is conducted by starting line at North and rotating clockwise to the desired angle, most probably the angle of the vector. Adding vectors, either two positive, two negative, or one of each is make most easily by resolving, or finding each vectors (A, B,C,) x and y compon ents. Here is an example of how to resolve then add vectors role See lab book.DataTrial 1Magnitude (g) heraldic bearing (Az)X (N)Y (N)A100.00001.00B100.0093.00.998-.052C100.00177.00.052-.998D100.00270.00-1.000TrialPercent Error (%)15.021.0338.2411.8Trial 2Magnitude (g)Direction (Az)X (N)Y (N)A120.00332.00-.5631.06B100.0075.00.966.259C100.00150.00.500-.866D100.00234.00-.809-.588Trial 3Magnitude (g)Direction (Az)X (N)Y (N)A170.00277.00-1.687.207B200.0060.001.7321.00C100.00148.00.530-.848D110.00215.00-.631-.901Trial 4Magnitude (g)Direction (Az)X (N)Y (N)A120.00315.00-.849.849B200.00339.00-.7171.867C300.00138.002.007-2.229D110.00265.00-1.096-.096Sample Calculations (Trial 2) Conclusion I successfully added three out of four vectors with a percent fracture of 12% or less, in which the acceptable percent error was 20% or less.Analysis Friction between the string and the pulley can have an effect on the lab because it makes the forces unnaturally low. To solve this problem, do in frict ion by vibrating the force table. Another source of error may come when someone is putting the weights on the hooks of the pulleys and neglects to add the 50 grams of the hooks to their total force pulling on that particular string.
