Is it possible to bend the path of the bullet like a movie Wanted?


Film effects Wanted a lot of viewers around the world Belktath stunning very much like a movie Matrix, and was one of the most shots so exciting is the way it was commended by Wesley (the hero of the movie) and trajectory in the air to the point that turned the idea into the center of debate many people around the the world.

Is it can actually bend or change the path of the bullet when they were launched by the laws of physics?

The film depicts the scene as follows: "Can Wesley and a group of extraordinary people who have extraordinary capabilities to deflect the path of the bullet that they give to avoid an obstacle on the way by moving their hand rapidly in a circular motion."


But the scientific truth says that body to change the course you should strongly influence by Newton's First Law, so once the shot was fired and leave the barrel of a gun goes in a straight line at speeds of up to 1000 meters per second. And about the same rate of up to hundreds of thousands of RPMs to balance on track.

If we consider that the distance that its forthcoming big shot would be put to the influence of gravity significantly lead to a path that takes the bullet curving form below.

Add to that the wind and air friction will lead to reduce the pace of the bullet and push.

As for the large number of laps would create a slight deviation in the path of the bullet because of the impact of the so-called Magnus force.

And the power of Magnus or Magnus effect is what happens when you hit the ball a way that they revolve around the same occurs to walk in a circular path (which is what commentators described the athletes that the ball made .

But if we take the scene that happened in the movie where the hero was able to bend the path of the bullet into the distance does not exceed the approximately 10 meters (slaughterhouse scene), all the factors we have mentioned are not enough at all to bend the bullet to avoid Angelina Jolie as he did.

But you could derail shot by moving the wrist in a circular fashion as shown film?
Of course not .. We can not ..
The reason, quite simply, is Newton's First Law, which took him all of us in the sciences.
To imagine a ball moving in a circular path .. By leaving this path goes in a straight line will continue in the rotation.
The reason is very simple .. Spin the ball in the circular path because there is a force affected by it for a spin in this path such as a wall, for example.
Disappeared if the force will disappear impact and the ball goes in a straight path at a constant speed according to Newton's First Law.

But ..

After all that we mentioned at the top .. It remains to mention something important


Publishing worlds of Qalevurna in 1998 and a research paper on the applications of electro-mechanical systems ultra-small micro-electro-mechanical systems or what is known by its acronym MEMS.

Scientists, namely Dr.. Shih Ming-Shu Chih-Ming Ho of the University of California Wed. Yoshong Tai Yu-Chong Tai of California Institute of Technology, and carried out research work for the behavior of ultra-small power adapters when they are surrounded by a flow of liquids. That the MEMS so small that size does not exceed one millionth of a meter.

If we imagine that it could put a sufficient number of these adapters will be allocated in the bullet shot then able to analyze and control the registration and on track. However, this research focuses on the uses of this technique in microbiology, For Wesley to search elsewhere.
