Question

When we say that momentum is "conserved," we mean The momentum of an object is the same before and after a collision. The momentum of the universe increases; it never decreases. The momentum of an isolated system is constant. If there are no forces acting on an object, its momentum is zero.

Step 1

When we say that momentum is "conserved," we mean that the total momentum of an isolated system remains constant if no external forces act upon it. This is known as the law of conservation of momentum. Show more…
