Best ResponseYou've already chosen the best response.0:)) here's another question.. The work done by a force is the product of force and distance. Does this means that the torque and work are equivalent?

Best ResponseYou've already chosen the best response.0One reason for that  GIVING GYROSCOPIC STABILITY to the bullet . This stability is due to angular momentum. When a body is spinning around some axis, we say the angular momentum is pointing along this axis with a magnitude equal to the magnitude of the angular momentum. When a body has angular momentum is some direction, much like with regular momentum, it doesn't like to have its magnitude or direction changed. One particular note to this is precession, where the angular momentum of a body spins about a 3rd axis, but it doesn't like to have this 3rd axis changed either. So, when the bullet has some spin, it has some angular momentum in the direction of its motion. This spinning adds stability, because the bullet itself doesn't want to turn on some other axis, thus changing the direction of its angular momentum, so it stays pointing straight. Since it stays pointing straight, it is more aerodynamic, so it flies for longer.
