Physics and Sports:
thought that this entry had already published some time ago, but I was wrong .. now I found when I went up the other.
Sometimes when we see a football game or a repetition of certain releases we keep the mouth open (at least to me if that ever happened to me xD). People tend to talk a lot about sports and the bus is a good place for it (a peak travel time and gives a lot of things ...) and even if you do not participate in the conversation as you learn to have them around. I came to my mind one of the conversations, and discuss how it gives the effect in some sports balls / balls.
Who has not ever released a shot with effect? Who has not tried to stop a throw threaded playing ping pong and the ball is gone for a walk?
Newton in the past and noticed the curved path of a spherical projectile that could follow a tennis ball because friction but the theory is known at present corresponds to a study by Magnus.
" The Magnus Effect could be explained as the shot in which the rotating ball creates a vortex of air around them, carrying the same direction as the flow of air which presents the ball, thus increasing the speed on that side of the ball. On the other side of the ball the vortex rotates in the opposite direction of airflow, which causes slow down due to friction, so the air pressure is lower on one side than another, causing a force perpendicular to the direction of the airflow that bypasses the area of \u200b\u200bhis career. "
therefore affects rotating bodies perpendicular to its movement through a fluid. When moving in the air is a resistance which depends on the relative velocity of the object from the air and in the case of the ball, this force is greater on one side than another.
"Wanted "
If we translate this into a movie like "Wanted" in which bullets are diverted from straight and around obstacles to reach the desired goal that is because there is a force that causes the bullet to make a rope and the force that causes this rope is a force that interacts with the bullet's flight.
Therefore, if you can deflect bullets as the Magnus effect, but one thing is divert .. and another to do the film.
leave here a trailer of the movie in case some do not know. That looks like fire and save the obstacle to reach the target of the fund.

also leave this web on aerodynamics in table tennis is very interesting.
