vector game story
Fang Heng was transmigrated to a parallel world and his soul was forced into the body of a man who had just committed suicide. Huh? What? Every human here was being forced to join a game? Those who refused would be killed? Wait? This suicide dude was a pro gamer? He had the highest S-rank talent sill, the Zombie Clone? Damn! The S-rank skill evolved! My zombie clones could auto hunt! [Your zombie army has crafted Wooden Axe x720 when you were offline. You have received 1921 experience points for the Basic Crafting skill.] [Your zombie army has chopped down 27,821 trees and gathered 128,973 pieces of wood while you were offline. You have received 2,171,921 experience points for the Basic Wood Chopping skill.] Just as the rest of the players were struggling to survive in the zombie apocalyptic game, Fang Heng's zombie clones were starting to clear every resource out of the forest. Hm... What an interesting game!
Vector Addition and Subtraction Suppose a particle undergoes a displacement followed by a second displacement . The final result is the same as if the particle had started at the same initial point and undergone a single displacement (Fig. 1.11a). We call displacement the vector sum, or resultant, of displacements and We express this relationship symbolically as (1.2) The boldface plus sign emphasizes that adding two vector quantities requires a geometrical process and is not the same operation as adding two scalar quantities such as In vector addition we usually place the tail of the second vector at the head, or tip, of the first vector (Fig. 1.11a). If we make the displacements and in reverse order, with first and second, the result is the same (Fig. 1.11b). Thus (1.3) This shows that the order of terms in a vector sum doesn’t matter. In other words, vector addition obeys the commutative law. Figure 1.11c shows another way to represent the vector sum: If vectors and are both drawn with their tails at the same point, vector is the diagonal of a parallelogram constructed with and as two adjacent sides. CAUTION Magnitudes in vector addition It’s a common error to conclude that if
