Vector Addition Formula:
From: | To: |
Vector addition is the operation of adding two or more vectors together into a vector sum. The sum of two vectors is obtained by adding their corresponding components.
The calculator uses the vector addition formula:
Where:
Explanation: Each component of the resulting vector is the algebraic sum of the corresponding components of the original vectors.
Details: Vector addition is fundamental in physics and engineering for combining forces, velocities, and other vector quantities. It's essential for understanding motion, electromagnetism, and structural analysis.
Tips: Enter the x, y, and z components for both vectors. The calculator will compute the sum of corresponding components. You can use positive or negative values as needed.
Q1: What's the difference between vector and scalar addition?
A: Vector addition considers both magnitude and direction (components), while scalar addition only considers magnitude.
Q2: Can I add vectors of different dimensions?
A: No, vectors must have the same number of components to be added.
Q3: What is the geometric interpretation of vector addition?
A: The sum vector is the diagonal of the parallelogram formed by the two vectors (parallelogram law).
Q4: Does vector addition follow commutative law?
A: Yes, vector addition is commutative: a + b = b + a.
Q5: How is vector subtraction related to addition?
A: Vector subtraction is equivalent to adding the negative of a vector (a - b = a + (-b)).
