conservation + of + momentum
The phrase is compositional: 'conservation' (preservation or keeping constant) combined with 'momentum' (the physical quantity of motion) yields the idea of preserving momentum. Although it is a technical physics term, the meaning is directly derivable from the constituents and follows a common 'conservation of X' pattern found across languages, so a learner who knows the parts would understand the basic sense.
Etymology
Conservation of momentum puts together conservation (keeping) and momentum ('motion amount') and comes from a simple image: if two ice skaters push each other, they slide apart, one moving one way and the other the opposite. So, if nothing pushes from outside, the total 'motion' they have stays the same, and that's why the phrase means the total motion in a group does not change.
