Calculated result
Enter values and select Calculate.
Classical momentum
p = mv; reverse modes solve mass or velocity after normalizing mass and speed units. kg·m/s and N·s are dimensionally equivalent.
Signed-motion boundary
Signed velocity and momentum are preserved as direction. This does not model collisions, injury, ballistics, crash severity, relativistic motion, or protective-equipment performance.
