Why is it impossible to curve a bullet like they do in the movie Wanted?

902 views

[I did see that this was answered a few years ago but the answer was a little too unscientific] I’m watching the movie and decided to Google it. All the answers are really physics heavy and I’m having trouble understanding. One answer even went on to speak about long distance military shooting, the rotation and curvature of the earth, and the fact that the bullet and earth themselves are both gyroscopes. The Magnus effect was mentioned as well. I still dont understand why it’s not possible.

For the same reason you can’t throw a book across the room and have it curve in a circle around you. In order to make something move or change its motion, you need an unbalanced force to act on it. A bullet is unguided. Once it leaves the barrel of the gun, there are no forces acting on it except gravity and air resistance. Gravity is going to pull the bullet straight down, and air resistance will slow the bullet down and maybe deviate its trajectory depending on the direction of and strength of the wind. There’s no force acting on the bullet that can make it curve around stuff.
