Formula and methodology
Formula: Potential energy U=mgh; kinetic energy K=1/2mv²; mechanical energy E=U+K.
The calculator reports each component before adding them, so the selected reference height and speed remain visible.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Mass — kg; minimum 0; maximum 1000000
- Height — m; minimum -1000000; maximum 1000000
- Speed — m/s; minimum 0; maximum 1000000
- Gravitational acceleration — m/s²; minimum 1.0E-6; maximum 1000
Worked example
| Input | Value |
|---|---|
| Mass | 2 |
| Height | 10 |
| Speed | 3 |
| Gravitational acceleration | 9.80665 |
Potential = 196.133 J; kinetic = 9 J; total = 205.133 J.
Assumptions and limits
- Mass and gravity are nonnegative with positive gravity; height may be signed relative to a chosen reference.
- Speed is a nonnegative magnitude and the system is modeled without nonconservative work.
- Rotation, friction, springs, relativity, and external energy transfer are not modeled.
