Vector addition in polar coordinates involves combining vectors described by their magnitude and direction angle. This method is essential in physics and engineering for analyzing forces, velocities, and other vector quantities.
The calculator uses vector addition formulas:
Where:
Explanation: The calculator converts polar coordinates to Cartesian components, sums the components, and calculates the resultant magnitude.
Details: Vector addition is fundamental in physics, engineering, and computer graphics for combining forces, velocities, accelerations, and other directional quantities to determine net effects.
Tips: Enter magnitudes as positive values and angles in radians. For degrees, convert to radians first (radians = degrees × π/180). Ensure all values are valid numerical inputs.
Q1: Why use radians instead of degrees?
A: Radians are the standard mathematical unit for angles in trigonometric functions and provide more natural calculations in physics and engineering.
Q2: Can I add more than two vectors?
A: This calculator handles two vectors. For more vectors, repeat the process by adding the resultant to the next vector sequentially.
Q3: What if my angles are in degrees?
A: Convert degrees to radians by multiplying by π/180 (approximately 0.0174533) before entering values.
Q4: How is the direction of the resultant determined?
A: The direction can be found using θ = atan2(R_y, R_x), which gives the angle in radians relative to the positive x-axis.
Q5: Are negative magnitudes allowed?
A: No, magnitudes represent length and must be non-negative. Direction is controlled by the angle parameter.
