SDT Formula Guide
The Kinematic Speed-Distance-Time trio maps the elementary equation of motion.
Clicking different quadrants of the interactive SVG triangle dynamically alters the calculated property:
- Speed (S): Computed as distance divided by elapsed time (d / t).
- Distance (D): Computed as traveling speed multiplied by traveling duration (S × t).
- Time (T): Computed as total distance divided by average velocity (d / S).
Common FAQs
What is the difference between speed and velocity?
Speed represents a scalar property mapping rate of position change without directional coordinate bias, whereas velocity represents a vector aligning rate and strict directional heading coordinates.
How is average speed calculated for multiple legs?
To resolve overall trip averages, calculate cumulative distance divided by cumulative time. Do not compute simple averages of individual leg speeds, as duration spent at each speed varies.
Why do we include Mach conversions?
Mach speed correlates object velocities against the localized speed of sound. Including Mach conversions allows aerospace engineers and enthusiasts to easily map sonic speed ratios.
