Question

multiple-choice question after the truck full of marbles transfers its momentum to the christmas ornament, what must equal the amount of momentum transferred? the sum of all the moving pieces of the ornament. the sum of all the moving pieces of ornament and moving marbles. rewatch skip

Explanation:

This question is about the conservation of momentum, a concept in Physics (subfield of Natural Science). According to the law of conservation of momentum, in a closed system, the total momentum before an interaction equals the total momentum after. When the truck transfers momentum to the ornament (and marbles, if they move), the sum of the momentum of all moving parts (ornament and marbles) should equal the momentum transferred (from the truck). The first option only considers the ornament, but if marbles are moving, their momentum must also be included. So the correct option is "The sum of all the moving pieces of ornament and moving marbles."

Answer:

The sum of all the moving pieces of ornament and moving marbles.
