Description
Apply supplied signed energy transfers to an opening energy balance.
Physical quantities require compatible units, coordinate directions, reference origins and model assumptions. Mass and weight, angular and cyclic frequency, particle velocity and wave speed are distinct quantities. Ideal single-axis, linear-spring and constant-torque terms describe supplied models rather than identify real material behavior or safe operating limits.
Apply supplied signed energy transfers to an opening energy balance.
When to use this tool
Use Energy Balance Signed Transfer when you already have openingEnergyJoules, signedTransfersJoules and need to apply supplied signed energy transfers to an opening energy balance.
How to use the tool and how it works
- Enter openingEnergyJoules, signedTransfersJoules. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read closingEnergyJoules. Use the output convention below.
Sum signedTransfersJoules starting at openingEnergyJoules, preserving signs.1

| signedTransfersJoules | Signed Transfers Joules | Required. Array of finite number; maximum items 256. |
| Output field | Interpretation | Returned shape |

}Limitations and assumptions
- The boundary and all transfer terms are supplied; no conservation audit, missing loss, work/heat separation or safe energy level is inferred.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the full force, energy or wave model with compatible reference frames and units for a physical prediction. Include changing loads, material behavior and losses when the ideal constant-parameter term no longer represents the system.
