Momentum and impulse calculator

Momentum measures how much motion an object has: p = m × v, the product of its mass and velocity, measured in kilograms-metres per second (kg·m/s).

Impulse is the change in momentum produced by a force acting over time: J = F × t = Δp, measured in newton-seconds (N·s), which are dimensionally the same as kg·m/s.
