- The momentum of a moving object depends on its mass and velocity.
- Momentum is a vector quantity.
- momentum (kg m/s) = mass (kg) x velocity (m/s)
Momentum is mass multiplied by velocity, so the units for momentum are a combinationof the units for mass and velocity.
When two objects collide, the total momentum before the collision is the same as the total momentum after the collision, providing no external forces act. Momentum is conserved.
