What is the project about?
This project introduces a new physical measurement standard: the NKTm (noun form), for the NKTg Law (Law of Varying Inertia). It explores the theory, dimensional analysis, real-data verification (Neptune / NASA JPL Horizons), and real-world applications in astronomy, engineering, earth sciences, etc.
Why this project matters
-
Existing physics laws (Newton, Joule, Watt…) use well-defined units; NKTg introduces varying inertia, a quantity combining position, mass, velocity (and optionally rate of change of mass).
-
Having a standard unit (NKTm) helps quantify phenomena where mass varies explicitly (mass loss/gain, variable-mass systems).
-
Enables more accurate modelling, simulation, and understanding of dynamics in bodies like planets, spacecraft, robotics, environmental systems.
What will you do / What’s been done so far
-
Theoretical formulation of NKTg Law: two expressions
• NKTg₁ = x · p (position-momentum interaction)
• NKTg₂ = (dm/dt) · p (mass-variation momentum) -
Dimensional analysis to show how NKTm relates to standard dimensions: [M·L²/T] or [M²·L/T²] depending on form.
-
Verification using NASA JPL Horizons data for Neptune (2023-2024): computing NKTg₁, NKTg₂, total NKTg.
-
Identification of domains of application: astronomy, aerospace, environmental / earth sciences, engineering.
What remains to do
-
Build physical / computational models to simulate varying-mass systems using NKTm (e.g. spacecraft with fuel consumption, objects losing mass)
-
Create more case studies: e.g. real satellite data, meteor showers, biological systems (mass loss/growth)
-
Visualizations & plots to show behaviour over time
-
Possibly hardware / sensor experiments: tracking mass change, motion, measuring inertia variation
-
Publish code, diagrams, documentation, share open-source tools or libraries
