Formula
p = m v
Momentum is mass times velocity. In closed systems, total momentum is conserved through collisions.
Worked example
3 kg at 8 m/s has momentum 24 kg·m/s.
Where this can give the wrong answer
- Velocity sign indicates direction on a chosen axis.
- Relativistic momentum needs γmv at high speeds.
- Angular momentum L = Iω is a different quantity.
FAQ
- Noether's theorem links spatial symmetry to conservation — central to collision analysis.
