Formula and methodology
Formula: Net work=½m(final speed²−initial speed²).
The result is positive when kinetic energy increases and negative when the object slows under the net work convention.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Mass — kg; minimum 1.0E-6; maximum 1000000000000
- Initial speed — m/s; minimum 0; maximum 1000000000
- Final speed — m/s; minimum 0; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Mass | 2 |
| Initial speed | 3 |
| Final speed | 7 |
Net work =40 J.
Assumptions and limits
- Mass and speeds are scalar magnitudes in compatible units.
- Net work includes the combined effect of all forces.
- Rotation, deformation, and relativistic speeds are not modeled.
