- Initial momentum
- 12000 kg·m/s
- Final momentum
- 0 kg·m/s
Quick answer
Momentum p = m x v; change in momentum = m x (v2 - v1).
delta p = m(v2 - v1)
How to use the Momentum Change Calculator

Frequently asked questions
What is the sign of the answer?
A negative change means momentum decreased in the chosen positive direction, such as during braking.
How does this relate to force?
Force = change in momentum divided by the time over which it happens.
