The Magnus effect is a phenomenon that occurs when a spinning object is moving through a fluid or gas (air). A lift force acts on the spinning object and its path may be deflected in a manner not present when it is not spinning. The strength and direction of the Magnus effect is dependent on the speed and direction of the rotation of the object ...
External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field.
In sports like tennis or volleyball, the player can use the Magnus effect to control the ball's trajectory (e.g. via topspin or backspin) during flight. In golf, the effect is responsible for slicing and hooking which are usually a detriment to the golfer, but also helps with increasing the range of a drive and other shots.
The Magnus Effect is something most people have never heard of until now that a YouTube clip explaining what it does showed how incredibly cool physics can be. These kids went to a 415-foot-high ...
The Buckau, the first vehicle to be propelled by a Flettner rotor. A Flettner rotor is a smooth cylinder with disc end plates which is spun along its long axis and, as air passes at right angles across it, the Magnus effect causes an aerodynamic force to be generated in the direction perpendicular to both the long axis and the direction of airflow.

Perhaps I'm misunderstanding but reading the section on the Magnus Effect, I can't tell what the difference is between this and the gyroscopic preservation of angular momentum. Is the Magnus effect a more specific name for this, used in balistics? or is there a difference which I didn't spot? 81.97.166.238 23:06, 30 October 2011 (UTC)
Just like kinetic-energy tank rounds, flechettes are too long and thin to be stabilized by rifling and perform best from a smoothbore barrel. The ACR program was abandoned due to reliability problems and poor terminal ballistics. [citation needed] Mortar barrels are typically muzzle-loading smoothbores. Since mortars fire bombs that are dropped ...
In the wake of Sayyed Hassan Nasrallah's killing, Hezbollah faces the enormous challenge of plugging the infiltration in its ranks that allowed its arch enemy Israel to destroy weapons sites ...
