To be "in irons" (i.e. to lose forward momentum) when changing tack. mizzen 1. A mizzen sail is a small sail (triangular or gaff) on a ketch or yawl set abaft the mizzenmast. [2] 2. A mizzen staysail is an occasional lightweight staysail on a ketch or yawl, set forward of the mizzenmast while reaching in light to moderate airs. [2] 3.
In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.
Recoil: The backward momentum of a gun when it is discharged. In technical terms, the recoil caused by the gun exactly balances the forward momentum of the projectile, according to Newton's third law. (often called kickback or simply kick). Recoil operation: An operating mechanism used in locked-breech, autoloading firearms. As the name implies ...
Once the ship has come about, the remaining sails are adjusted to align properly with the new tack. Because square-rigger masts are more strongly supported from behind than from ahead, tacking is a dangerous procedure in strong winds. The ship may lose forward momentum (become caught in stays) and the rigging may fail from the wind coming from ...
The side chosen can be based on the wind and/or current direction, so the stern paddler's forward strokes are pushing the boat in the opposite direction the wind and/or current is, reducing the number of J-strokes required to keep forward momentum; or sides can be chosen based on the paddlers' stronger side, since this is more comfortable and ...
Gainer – A back flip that ends with the performer moving forward from the starting point due to forward momentum. Loser – A front flip that ends with the performer moving behind the starting position due to backward momentum. Switch – A flip that is launched from and lands on the same leg.

The gun acquires a rearward velocity that is ratio of this momentum by the mass of the gun: the heavier the gun, the slower the rearward velocity. As an example, a 8 g (124 gr) bullet of 9×19mm Parabellum flying forward at 350 m/s muzzle speed generates a momentum to push a 0.8 kg pistol firing it at 3.5 m/s rearward, if unopposed by the shooter.
