The Parallel Vector Calculator simplifies the process of finding the component of one vector that is parallel to another. This function is particularly useful when dealing with forces, velocities, or any other vector quantities in science and engineering. By understanding how vectors align with each other, professionals and students can better analyze dynamics, structural loads, and other vector-dependent phenomena.

Formula of Parallel Vector Calculator

To find the parallel component of a vector, certain mathematical formulas are used:

  1. Dot Product of Vectors: The dot product is calculated as: dotProduct = Ax * Bx + Ay * By + Az * Bz
  2. Magnitude of Vector B: The magnitude is found using the equation: magnitudeB = sqrt(Bx^2 + By^2 + Bz^2)
  3. Parallel Component of Vector A along Vector B: The formula to find the parallel component is: A_parallel_B = (dotProduct / magnitudeB^2) * B

Steps to calculate the parallel component of A along B:

  1. Calculate the Dot Product:
    • Formula: dotProduct = Ax * Bx + Ay * By + Az * Bz
    • Calculation: dotProduct = 3 * 1 + 4 * 2 + 0 * 0 = 11
  2. Calculate the Magnitude of Vector B:
    • Formula: magnitudeB = sqrt(Bx^2 + By^2 + Bz^2)
    • Calculation: magnitudeB = sqrt(1^2 + 2^2 + 0^2) = sqrt(5)
  3. Find the Parallel Component of A along B:
    • Formula: A_parallel_B = (dotProduct / magnitudeB^2) * B
    • Calculation: A_parallel_B = (11 / 5) * (1, 2, 0) = (11/5, 22/5, 0)

Result: The parallel component of vector A along vector B is (11/5, 22/5, 0).
