Momentum is conserved in both directions.

Equations and live calculation

Vector momentum: p = m × vResolve every momentum into x and y components.

Conservation: Σp before = Σp afterpx and py totals remain constant.

Restitution: e = separation speed ÷ approach speedElasticity controls the kinetic energy retained.
