Velocity Transformation Formula:
From: | To: |
Definition: This calculator transforms inertial velocity measurements into body-coordinate velocities using a transformation matrix.
Purpose: It helps engineers and physicists analyze motion in body-fixed reference frames, commonly used in aerospace and mechanical systems.
The calculator uses the formula:
Where:
Explanation: The inertial velocity is transformed using direction cosine matrices based on the orientation angle.
Details: Proper coordinate transformation is essential for accurate navigation, control systems, and motion analysis in rotating reference frames.
Tips: Enter the inertial velocity in m/s and the transformation angle in degrees (0-360). The angle represents the orientation between coordinate systems.
Q1: What's the difference between inertial and body coordinates?
A: Inertial coordinates are fixed in space while body coordinates move with the object.
Q2: Why is angle input important?
A: The angle defines the orientation between coordinate systems, affecting the transformation.
Q3: What happens at 90 degrees?
A: At 90°, the body-coordinate velocity would be zero as it's perpendicular to the inertial velocity.
Q4: Can this handle 3D transformations?
A: This simplified version handles 2D cases. For 3D, you'd need Euler angles or quaternions.
Q5: What units are used?
A: Velocity is in meters per second (m/s) and angles in degrees (0-360).
