What the impulse calculator solves
Use the impulse calculator for collisions, sports impacts, and physics problems involving force over time.
Formula
How to use it
- Choose the quantity you want to solve for.
- Enter the known values with consistent units.
- Check the rearranged formula, substitution, and warnings before using the result.
How to read the answer
Impulse equals the change in momentum when the force-time model matches the event.
Common mistakes and edge cases
- Use average force if force changes over time.
- Time must be in seconds for N s.
- Impulse has direction when force has direction.

Frequently asked questions
Can the impulse calculator solve for a missing variable?+
Yes. Use the solve-for control to hide the missing value, then enter the other known values with compatible units.
Why do the units matter?+
Formula calculators assume the entered values are already in matching units. Convert first when your measurements use mixed systems.
