Momentum is always conserved. The momenta of individual objects in a system may vary, but the vector sum of all the momenta will not change. Therefore, momentum is said to be conserved.

The conservation of momentum in a glancing collision between two objects is expressed as


The conservation of momentum in a collision between two objects where the two objects become one is expressed as
