"Conservation of momentum."
More precisely: in an isolated system (no external net force) the total momentum vector is constant during a collision. Mathematically for two bodies:
m1 v1 + m2 v2 = m1 v1' + m2 v2'.
This follows from Newton's third law (internal forces are equal and opposite) and holds for elastic and inelastic collisions alike; kinetic energy is only conserved in elastic collisions. If a net external force acts, the total momentum changes by the impulse of that external force.
