According to the law of conservation of momentum, a bowling ball...?

Question

will not change velocity when it hits the pins? true or false

Answer 1

False, for the reasons given in the previous 2 answers. And the law of conservation of momentum doesn't work the way you might think; the momentum of the whole system is conserved, and the system includes not only the ball and pins but the bowling alley, town, state, country and planet! Thus the ball and pins eventually stop moving relative to the rest of the system and that is what you see, yet momentum is conserved.

Answer 2

false, the energy of the bowling ball is transfered to the pins. Also, velocity is a measure of speed as well as direction, so when the ball hits the pins the bowling ball glances off them, not much, but some.

Answer 3

the guidelines of angular momentum did not exist in the few planck cases after the large bang. So the form ought to not violate rules that weren't existence. Inflation is a contemporary thought that has promise as to how the universe expanded so with out postpone. B

Answer 4

false ... won't change much ... but if the bowling pins *start* moving, they have "gained" momentum ... meaning that the bowling ball has "lost" momentum ... since total momentum must remain constant

Answer 5

False. There's a collision. Ball slows down; pins speed up. Jeez, get a clue.

Answer 6

False, imagine 10,000 pins.
