What this calculator does

Calculate impulse and momentum change from mass and initial/final velocity.

How it works

The calculator evaluates J = Δp = m(vf − vi); average force = J ÷ Δt. Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.
