WebThe magnitude of vector →D is D = √D2x + D2y = √(−4.0cm)2 + (2.9cm)2 = √(4.0)2 + (2.9)2cm = 4.9cm. The direction angle is tanθ = Dy Dx = + 2.9cm −4.0cm = −0.725 ⇒ θ = tan−1(−0.725) = −35.9°. Vector →D lies in the second quadrant, so its direction angle is θD = θ + 180° = −35.9° + 180° = 144.1°. Check Your Understanding 2.5 WebSep 3, 2024 · A vector in a plane is represented by a directed line segment (an arrow). The endpoints of the segment are called the initial point and the terminal point of the vector. An arrow from the initial point to the terminal point indicates the direction of the vector. The length of the line segment represents its magnitude.
WebThe magnitude and direction of the sum of two or more vectors can also be determined by use of an accurately drawn scaled vector diagram. Using a scaled diagram, the head-to-tail method is employed to determine the vector sum or resultant. A common Physics lab involves a vector walk.
