Good luck blowing the wings off and leaving the fly intact, Wesley, no matter how supernaturally accurate a shot you are.

Angelina Jolie can teach you a lot of things, but don't let her teach you physics.
I wish you had consulted with me before posting this. As the Chair of Bysiemdnff Physics at Smurf University, I could have easily explained how Wesley appears to "bend" the trajectory of a bullet shot from his gun.
What Wesley or the shooter is doing is actually creating the "illusion" of the bullet bending. The bullet launch appears to be centered from the firearm barrel. However, the gun has been modified to angle the bullet slightly away upon firing. This optical deviation, combined with the impact of the bullet into the observer's brain, creates the impression upon the viewer that the bullet has traveled in a "bending" path from the pistol. The A.
That a bread truck could keep up with a sports car, however Note that there are guided bullets prototyped at Sandia that change trajectory to track a laser target. And that there are smart munitions that explode after N distance is flown. Add a comment. You can see why the writers might think the example of a curveball makes this plausible, but a little more knowledge of physics shows this doesn't make sense. Changing the path of a moving object means changing the momentum vector, done by applying a force for some time, since change in momentum is force integrated over time.
With a curveball this force is due to different air pressures on each side, created by its spin and stitching; but a bullet has a much larger momentum than a ball, and there's much less time for the air to apply a force to it, so the change to its direction would be tiny.
Link on the physics of curveballs, if anyone's curious: ffden Actually, I may have failed to take into account that because the bullet is moving faster, the force the air exerts on it is much greater, which could balance out the smaller time the force is exerted; Patrick Hughes mentioned the guided bullets from Sandia above, and I found an article at share.
The video at youtube. Just so we're on the same page, here are Newton's laws or Motion: First law: If an object experiences no net force, then its velocity is constant: the object is either at rest if its velocity is zero , or it moves in a straight line with constant speed if its velocity is nonzero.
Second law: The acceleration a of a body is parallel and directly proportional to the net force F acting on the body, is in the direction of the net force, and is inversely proportional to the mass m of the body, i. This means that F1 and F2 are equal in magnitude and opposite in direction. One other possibility would be to have the bullet itself expel some highly pressurized gas in a sideways direction, pushing it in the opposite direction like a rocket, but I don't think this is consistent with how the bullets were depicted in Wanted.
To quote Matrix, "The mind makes it real". DarkWulf DarkWulf 1. Do you have anything to support this or is it headcanon? Do you have any reason sourced in the movie itself or related works to pull in ESP-type powers? Especially since they seem to explicitly try to justify the ability in real-world terms.
This seems like a personal theory, not something supported by the source material. No, but given that no amount of an adrenaline rush is gonna allow you to curve a bullet even a little bit, a more plausible explanation might be an esp-like one, specially given that if you look at real life people can do and achieve some weird things that can't always be explained by science as we know it right now.

Delany ends Nov Featured on Meta. Ok, back to the bullet. So, why would a bullet curve? For something to change direction of motion, there must be a force acting on it. Instead of calculating the motion of a spinning bullet or something, I am just going to determine the force needed to make a bullet curve.
That force can then be compared to other forces like gravity and air resistance. How does a force make an object curve? If you want to think about it in terms of force and acceleration, the acceleration of an object moving in a circle is:.
The negative and the r-hat indicate that the acceleration is towards the center of the circle. So, what do I need to calculate this force to move in a circle? For the circle, first I am using a circular path just because it is a little easier.
I know the bullet might be able to do something else weird, but I am ok with that. How do I estimate the radius for a bullet? First it curves away from the person in the middle and then curves back to the target behind her. If I just look at the first curve, I can estimate the distance from the person and the deflection.
From this, I can calculate the radius of the circle. Here is a picture.
