| Symbol | Quantity | Unit | Meaning | Usual range |
|---|---|---|---|---|
J | impulse | N*s | Change in momentum delivered by the force | 0 to 1e+07 |
F | average force | N | Average force during the contact | 0 to 1e+07 |
t | contact time | s | Duration of the force | 0 to 1000 |
Assumptions
- Force is averaged over the contact time
Valid when
- Speeds far below the speed of light
