About this calculator
Overview
Momentum is the product of mass and velocity. It is a vector quantity that represents the 'strength' or 'quantity' of motion. In any isolated system, the total momentum remains constant according to the law of conservation of momentum.
💡
Pro Tips
SI units for momentum are kg·m/s or N·s.
Because velocity is a vector, momentum also has a direction. This calculator solves for the magnitude.
The change in momentum is called 'Impulse' and is equal to the force applied over a period of time.

Fun Facts
"A massive ship moving slowly can have much more momentum than a high-speed bullet because of its enormous mass."
"Isaac Newton's famous second law, F=ma, is actually a simplified version of the more general F=Δp/Δt (force is the rate of change of momentum)."
"Conservation of momentum is why a gun recoils when fired and why rockets can move in the vacuum of space."
