The Distance Formula In week one‚ we learned a simple yet extremely useful math concept‚ the Distance Formula. This formula uses the Pythagorean Theorem to determine the distance between two points on the rectangular coordinate system. Variations of the Pythagorean Theorem such as the Distance Formula can be used in building things or making plans to build something. Scenario Suppose you are volunteering at the local community center. The community center committee is planning to install

Understanding Projection & Views Orthographic Projection Orthographic Projection is a way of visualizing different views of an object from there different sides such as a top view‚ front view‚ side view‚ the object is rotated so that the viewer viewing the object can see each individual side as the part is rotated. These Views are then drawn on a sheet of paper‚ enough views are drawn of the object to Help the person manufacturing the part to get a good visualization of what the part looks Like

Multiple Choice Question 6.31 A 1000-kg car moving at 10 m/s brakes to a stop in 5 s. The average braking force is 3000 N 5000 N 2000 N ***(answer) 1000 N 4000 N Force = mass x acceleration. Acceleration = velocity/time = -10/5 = -2 m/s/s. (- sign means a deceleration from velocity of 10 to 0) Force = 1000 x -2 = -2000 Newtons (i.e. 2000N in opposite direction to motion) Multiple Choice Question 6.11 When you jump from an elevated position you usually bend your knees upon reaching

Resolution of vector Introduction: The main objective of this lab is to add and resolve vectors using three distinct methods. 1) Graphical: When two forces act upon an object‚ their combined effect can be determined by adding the vectors‚ which represent forces. One method of performing this addition is known as graphical method of vector addition. In this method‚ arrows are drawn in the direction of forces. The lengths of arrows are proportional to the magnitude of vectors. The resultant
