sci.total-energy-relativistic Calculator
Calculates total relativistic energy E = γmc² and rest energy E₀ = mc², with kinetic energy KE = (γ−1)mc². A 1 kg mass has rest energy 9 × 10¹⁶ J — equal to the annual electricity output of 12 nuclear power plants.
Inputs
Mass Kg
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
Velocity Pct C
Speed in a specified direction (m/s). Required for momentum, kinetic energy, and wave calculations.
Results
total relativistic energy (J)
The combined total across all inputs and components.
rest energy E₀=m₀c² (J)
Sample size or count used in the calculation.
kinetic energy (J)
Energy of motion: KE = ½mv². Scales with the SQUARE of velocity — doubling speed quadruples kinetic energy. This is why crash severity grows so rapidly with speed.
Lorentz factor γ
A dimensionless multiplier applied in the calculation.
E_total = γm₀c²
The combined total across all inputs and components.
