What can the law of conservation of momentum predict?
Conservation of momentum (or the law of such) says that when two or more bodies collide that the net momentum of the system will remain the same (ie. be conserved). from wikipedia… In classical mechanics, momentum (pl. momenta; SI unit kg·m/s, or, equivalently, N·s) is the product of the mass and velocity of an object (p=mv). For more accurate measures of momentum, see the section “modern definitions of momentum” on this page. It is sometimes referred to as linear momentum to distinguish it from the related subject of angular momentum. Linear momentum is a vector quantity, since it has a direction as well as a magnitude. Angular momentum is a pseudovector quantity because it gains an additional sign flip under an improper rotation the total momentum of any groups of objects remains the same unless outside forces act on the object. Momentum is a conserved quantity, meaning that the total momentum of any closed system (one not affected by external forces) cannot change.
