ENGINEERING PRINCIPLE
Impulse equals the change in momentum produced by a force over time.
Calculate impulse from average force and duration.
FORMULA & VARIABLES
J = F × Δt
- J = impulse (N·s)
- F = average force (N)
- Δt = force duration (s)
CALCULATION STEPS
How this result is assembled
- Convert the entered values to the SI basis required by the formula.
- Apply J = F × Δt using the current inputs.
- Present the result as 600 N·s and review the stated assumptions.
FORMULA VERIFICATION
Units, scope and reference
Reference: NIST SP 811 for unit relationships; standard classical mechanics and strength-of-materials derivations for the stated scalar relation.
Internal basis: All inputs are converted to the calculator’s SI base before the formula is evaluated.
Valid conditions: Positive finite scalar input values in the current calculator model.
Limitations: The entered force is a time-average over the interval. Direction is not represented in this scalar result.
ASSUMPTIONS
Use this result in context
- The entered force is a time-average over the interval.
