Name PHY-289 BERGEN COMMUNITY COLLEGE CALCULUS PHYSICS I Spring 2015 LAB 6 The Addition and Resolution of Vectors: The Force Table Report By: Name Date of Experiment: March 4, 2015 Date Report Due: March 11, 2015 Date Report Submitted : March 11, 2015 Partners: Page 1 of 11
Name Objective: To find the resultant or vector sum of two or more vectors, special methods of vector addition are used, which may be graphical and or analytical. These two methods will be further investigated in this lab and the graphical and analytical methods will then be compared with the experimental data obtained from the force table. Using the force table will help show the physical principles vector addition. Equipment Used: Force table with four pulleys Four weight hangers Set of slotted weights (masses), Including three of 50g and three 100g String Protractor Ruler Level 3 Sheets of Cartesian Paper Vector Addition I: Graphical and Analytical Method: Page 2 of 11
Name Graphical : After plotting the two Vectors a resultant can then be drawn in to see the resulting vectoring. Using the information given and a protractor, the direction is found as well as the magnitude. For this graph you can see that the resultant vector had a length of 5cm and a force of 0.285g. This was found using Pythagorean Theorem. Also the direction that was found graphically was 75 ° . Pythagorean Theorem Formula used : a 2 + b 2 = c 2 ( A = onesideof the triangle ,B = one sideof the triangle ,C = the hypotenuse ) Analytical : Breaking up the two vector forces into components then adding them together we find that the Resultant vector force to be 0.283g, and using the inverse Tangent function the angle of the Resultant force is found to be 75 ° .
