Vector Sum Equation:
From: | To: |
Vector addition is the operation of combining two or more vectors into a single vector called the resultant. In physics and engineering, this is essential for understanding forces, velocities, and other vector quantities.
The calculator uses component-wise addition:
Where:
Physics: Calculating net force, combining velocities, analyzing electric fields.
Engineering: Structural analysis, fluid dynamics, robotics.
Computer Graphics: Object movement, lighting calculations.
Instructions: Enter the x, y, z components for each vector. The calculator will compute the resultant vector and its magnitude.
Q1: What's the difference between vector and scalar addition?
A: Vector addition considers both magnitude and direction, while scalar addition only considers magnitude.
Q2: How is the magnitude calculated?
A: Magnitude = √(Rx2 + Ry2 + Rz2)
Q3: Can I add more than 3 vectors?
A: Yes, by adding vectors two at a time or by extending the formula for more vectors.
Q4: What if I only have 2D vectors?
A: Simply set the z-components to zero.
Q5: Does order of addition matter?
A: No, vector addition is commutative (A+B+C = C+B+A).
