select all that apply\nthe conservation of momentum ______.\n□ only applies to solid collisions where the objects bounce off each other\n□ requires that an object will not change velocity unless acted on by an outside force\n□ means that the momentum of a group of objects cannot change unless external forces act
Answer
Brief Explanations:
The conservation of momentum applies to all closed - system interactions, not just solid - object bounces. Newton's first law (an object will not change velocity unless acted on by an outside force) is a different concept. The conservation of momentum states that the total momentum of a closed system of objects remains constant unless external forces act on the system.
Answer:
The correct option is: means that the momentum of a group of objects cannot change unless external forces act.
