Lab Report :: essays research papers
Hypothesis I mass successfully add vectors.Introduction A vector is a quantity that has order of magnitude (speed, force, and/or length) and direction. For example, if a mortal is traveling East at 60 mph, then 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 sense to say the perspirer costs $38.00 southwest, so we leave off the direction. The magnitude symbol ( ), an arrow, can express direction by its angle on a adjust plane and its length, which is usually offered. In this science laboratory, I also use the directional measurement unit of Azimuth (Az), which is conducted by starting at conglutination and rotating clockwise to the desired angle, most probably the angle of the vector. Adding vectors, either ii positive, two negative, or one of each is done most good by resolving, or finding each vectors (A, B,C,) x and y component s. present is an example of how to resolve then add vectorsProcedure See lab book.Data trial run 1Magnitude (g) mission (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 collar out of four vectors with a percent error of 12% or less, in which the acceptable percent error was 20% or less. abstract Friction between the string and the pulley can have an yield on the lab because it makes the forces unnaturally low. To solve this problem, nullify fric tion by vibrating the force table. Another source of error may come when mortal is putting the weights on the hooks of the pulleys and neglects to add the 50 grams of the hooks to their kernel force pulling on that particular string.
