NKTm Unit: Measurement Standard for Varying Inertia in the NKTg Law

In physics, every fundamental law is associated with a characteristic quantity and its unit of measurement: Newton for force, Pascal for pressure, Joule for energy…
The NKTg Law (Law of Varying Inertia) proposes the existence of a new physical quantity — varying inertia — reflecting the interaction between position, velocity, and mass.
The NKTm unit is established as the measurement standard for varying inertia, with dimensional analysis and verification using NASA data (Neptune 2023–2024). The results show that NKTm is a new fundamental unit, independent of Newton, Joule, and Watt, with value in both astronomy and engineering.
1. Theoretical Basis
The NKTg Law describes the tendency of motion under the simultaneous effect of position, velocity, and mass:
NKTg = f(x, v, m)
Where:
• x: position (Length, [L])
• v: velocity (Length/Time, [L/T])
• m: mass (Mass, [M])
p = m⋅v: linear momentum (Momentum, [M•L/T])
Two fundamental expressions of the law:
• NKTg₁ = x⋅p
• NKTg₂ = (dm/dt)⋅p
Both characterize varying inertia, and are measured by a common unit called NKTm.
