Formula and methodology
Formula: Speed=√(2×kinetic energy/electron mass), with electron mass 9.1093837×10^-31 kg.
The page applies the classical kinetic-energy relationship and labels the result as non-relativistic so it is not mistaken for a high-energy particle solver.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Kinetic energy — minimum 0; maximum 1.0E-12
Worked example
| Input | Value |
|---|---|
| Kinetic energy | 1.0E-17 |
Electron speed ≈4.686×10^6 m/s.
Assumptions and limits
- Kinetic energy is supplied in joules and is within the non-relativistic model range.
- The particle is an electron with the stated rest mass.
- Relativistic corrections, fields, radiation, collisions, and quantum-state effects are not modeled.
