Answer 2

very true

Answer 3

excuse me very false

Answer 4

momentum is always conserved

Answer 5

false

Answer 6

False indeed. Thanks to the spatial symmetry of our universe, momentum is always always conserved. You should take a glance at Noether's Theorem (if you are familiar with the Lagrangian).

Answer 7

Oh, come on z_t, now you're just showing off.
ಠ_ಠ

I doubt that someone unfamiliar with introductory physics will know anything about Lagrangians.

Answer 8

yes i have no idea but now i know momentum is always conserved thanks alot everybody
