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.
English: When a soccer ball is kicked with a counter-clockwise spin, low pressure occurs when the airflow is in the same direction as the spin on the ball and high pressure occurs when the airflow is in the opposite direction as the spin on the ball.
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 ...

In certain conditions, the lift coefficient can even be negative, changing the direction of the Magnus force (reverse Magnus effect). [4] [13] [14] 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.
Magnus effect rotating kites (wing flipping or wing tumbling) that have the rotation axis bluntly normal to the stream direction use autorotation; a net lift is possible that lifts the kite and payload to altitude. The Rotoplane, the UFO rotating kite, and the Skybow rotating ribbon arch kite use the Magnus effect resulting from the ...
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
