Windage

Windage is a force created on an object by friction when there is relative movement between air and the object.

There are two possible causes of windage:

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

• the object is moving and being slowed by resistance from the air
• a wind is blowing producing a force on the object

The term can refer to :

• either, the effect of the force, for example the deflection of a missile or an aircraft by a cross wind
• or, the area and shape of the object that make it susceptible to friction, for example those parts of a boat that are exposed to the wind.

Aerodynamic streamlining can be used to reduce windage.

There is a similar hydrodynamic effect to windage.

In firearms parlance, windage refers to the side-to-side adjustment of a rifle's sight, used to change the horizontal component of the aiming point. (The up-down adjustment for the vertical component is the elevation.) It can also refer to the difference in diameter between the bore and the shot especially in muskets and cannon.

Force: In physics, a force is an external cause responsible for any change of a physical system. For instance, a person holding a dog by a rope is experiencing the force applied by the rope on his hand, and the cause for its pulling forward is the force exercised by the rope. The kinetic expression of th...
