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.
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 ...
In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases will be mathematically balanced out by an equal and opposite momentum ...
Positive ends – The possibility of taking advantage of a new security environment to create conditions for long-term peace – Wass de Czege; Primary Trinity – (1) primordial violence, hatred, and enmity; (2) the play of chance and probability; and (3) war's element of subordination to rational policy – Clausewitz
The left-hand side is the time derivative of the momentum, and the right-hand side is the force, represented in terms of the potential energy. [ 9 ] : 737 Landau and Lifshitz argue that the Lagrangian formulation makes the conceptual content of classical mechanics more clear than starting with Newton's laws. [ 27 ]
In sailing, heaving to (to heave to and to be hove to) is a way of slowing a sailing vessel's forward progress, as well as fixing the helm and sail positions so that the vessel does not have to be steered. [1] It is commonly used for a "break"; this may be to wait for the tide before proceeding, or to wait out a strong or contrary wind.
The spoken command "Hut!" is sometimes used by the stern paddler to alert the person paddling the bow to switch sides, giving rise to the term "Hut stroke". This technique is intended to avoid correction strokes after the forward stroke to make a very high stroke frequency possible thus enabling paddling with high speeds for a long time.
Adequate muscle strength is also required to execute a front aerial. In particular, the calf muscle of the leading leg is responsible for imparting additional upward momentum to the body at the final moment of launch. The total upward momentum must be sufficient to keep the performer aloft while the lower body completes its rotation about the ...
