Impulse-momentum theorem
Momentum · id impulse_momentum
F t = m v - m v_0
| Symbol | Quantity | Unit | Meaning | Usual range |
|---|---|---|---|---|
F | average force | N | Average net force during the interval | 0 to 1e+07 |
t | contact time | s | Duration of the force | 0 to 1000 |
m | mass | kg | Mass of the object | 0.001 to 1e+07 |
v | final velocity | m/s | Velocity after the force acts | 0 to 1000 |
v0 | initial velocity | m/s | Velocity before the force acts | 0 to 1000 |
Assumptions
- Constant mass
- Motion along a single line
Valid when
- Speeds far below the speed of light
