How it works
Impulse = average net force × duration. It equals the signed change in linear momentum.
Input definitions
- Average net force (N)
- Enter the value in the labeled unit.
- Time interval (s)
- Enter the value in the labeled unit.
A worked example
- Average net force (N)
- 20
- Time interval (s)
- 0.5
Assumptions & limits
Ideal educational model in the stated SI units. Real equipment, structural design and safety decisions need appropriate professional analysis; losses are excluded unless entered.

Common questions
Must the force be constant?
No, but enter its time average over the interval. Multiplying an instantaneous peak by the whole duration can overestimate impulse.
How does Impulse and momentum change work?
Impulse = average net force × duration. It equals the signed change in linear momentum.
What should I check before using Impulse and momentum change?
