External ballistics. This schlieren image of a bullet travelling in free-flight demonstrates the air-pressure dynamics surrounding the bullet. 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 ...
Resistance. Resistance is a series of first-person shooter and third-person shooter video games developed by Insomniac Games and published by Sony Computer Entertainment for the PlayStation 3, PlayStation Portable and PlayStation Vita video game consoles. The series takes place in an alternate history 1950s, in which an alien civilization known ...
In aerodynamics, aerodynamic drag, also known as air resistance, is the fluid drag force that acts on any moving solid body in the direction of the air's freestream flow. [ 23 ] From the body's perspective (near-field approach), the drag results from forces due to pressure distributions over the body surface, symbolized D p r {\displaystyle D ...
Projectile motion. Parabolic trajectories of water jets. Components of initial velocity of parabolic throwing. Ballistic trajectories are parabolic if gravity is homogeneous and elliptic if it is radial. Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected in a gravitational field, such as ...

The game was developed by Nihilistic Software and published by Sony Computer Entertainment in May 2012. It was announced in August 2011 at Gamescom. In the game, players control the character of Tom ...
Terminal velocity. The downward force of gravity (Fg) equals the restraining force of drag (Fd) plus the buoyancy. The net force on the object is zero, and the result is that the velocity of the object remains constant. Terminal velocity is the maximum speed attainable by an object as it falls through a fluid (air is the most common example).
Sep. 19—Beginning Thursday morning, the military airmen of Fairchild Air Force Base marched all day and through the night in memory of those who have been prison ers of war or missing in action.
