the recoil of the gun when fired is bcuz the initial momentum is zero.true or false?

Answer 1

Not really. The recoil is a rocket-like action. A closed pressurized chamber has the internal pressure exert equal forces in all directions and hence does not recoil in any particular direction. When suddenly a section of the wall is opened to make a hole, the force due to the previous pressure on that hole’s wall section disappears letting the opposite-direction pressure force to recoil the chamber.

Answer 2

False. Whatever the initial momentum, the gun will still recoil when fired.

Answer 3

yes its zero momentum is mass*velsity int it?
