Abstract

Classical mechanics employs energy as a bookkeeping construct, multiplying mass by specific mechanical energy to track motion. However, this approach introduces a structural inconsistency: mass is treated as a real stored capacity, while energy-per-mass remains a non-substantial abstraction. Extended Classical Mechanics (ECM) resolves this inconsistency by treating kinetic energy as a physically manifested portion of stored mass-existence, establishing a consistent mass-energy partition framework applicable to motion and gravitational potentials.

1. Dynamic Response in Classical Mechanics

Newton's second law provides the basic relationship between force, mass, and acceleration:

F = ma

For a constant force and non-zero mass:

a ∝ m⁻¹

Thus, as mass increases, acceleration decreases, indicating that mass functions as a stored resistance to motion.

2. Energy Partition Assumption in Classical Mechanics

Classical mechanics defines potential and kinetic energy as:

PE = mgh  ,  KE = ½mv²

Total mechanical energy is expressed as:

E = m(gh + ½v²)

Here, (gh + ½v²) is a bookkeeping quantity, a numerical abstraction per unit mass. Yet, classical theory simultaneously assumes PE ≥ KE, meaning only part of stored capacity manifests as motion.

3. Hidden Bookkeeping Inconsistency

True bookkeeping requires symmetric cancellation:

(gh + ½v²)/(gh + ½v²) = 1

However, the ratio m/(gh + ½v²) has incompatible units and lacks physical meaning, revealing a structural inconsistency. Mass is treated as a real stored capacity, while energy-per-mass is a non-substantial abstraction. Conservation of energy becomes numerical rather than physical.

4. Physical Correction: Consistent Bookkeeping

m⁻¹ → Δm  when a > 0,   with m ≥ Δm

Kinetic energy is thus interpreted as a physically manifested mass-equivalent portion, ensuring that stored capacity and motion are connected, not merely multiplied numerically.

5. Extended Classical Mechanics (ECM) Formulation

ECM formalizes this partition as:

(PEᴇᴄᴍ − ΔPEᴇᴄᴍ) + ΔKEᴇᴄᴍ,   with ΔKEᴇᴄᴍ = −ΔPEᴇᴄᴍ

Translating to mass-existence terms:

(Mᴍ − ΔMᴍ) + ΔMᴍ   when aᵉᶠᶠ > 0

This yields a dynamic system of:

Mᵉᶠᶠ + ΔMᴍ

representing motion or gravitational potential difference, where mass-energy transfer is physically realized rather than treated abstractly.

Conclusion

Classical mechanics, while effective at predicting motion, treats energy as a numerical bookkeeping tool rather than a physical substance. ECM restores physical meaning by partitioning stored mass-existence into manifested kinetic energy, ensuring consistent bookkeeping, dynamical response, and gravitational interpretation. This principle-driven approach bridges classical foundations with physically grounded mass-energy dynamics.
