Recoil (often called knockback, kickback or simply kick) is 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 and exhaust gases (ejecta), according to Newton's third law. In most small arms, the momentum is transferred to the ground through the body of the shooter; while in heavier guns such as mounted machine guns or cannons, the momentum is transferred to the ground through its mount. In order to bring the gun to a halt, a forward counter-recoil force must be applied to the gun over a period of time. Generally, the counter-recoil force is smaller than the recoil force, and is applied over a time period that is longer than the time that the recoil force is being applied (i.e. the time during which the ejecta are still in the barrel of the gun). This imbalance of forces causes the gun to move backward until it is motionless.
A change in momentum results in a force, which according to Newton's second law is equal to the time derivative of the momentum of the gun. The momentum is equal to the mass of the gun multiplied by its velocity. This backward momentum is equal in magnitude, by the law of conservation of momentum, to the forward momentum of the ejecta (projectile(s), wad, propellant gases, etc...) from the gun. If the mass and velocity of the ejecta are known, it is possible to calculate a gun’s momentum and thus the energy. In practice, it is often simpler to derive the gun’s energy directly with a reading from a ballistic pendulum or ballistic chronograph.
This is an alphabetical List of G.I. Joe: A Real American Hero characters whose code names start with the letters M-R.
Mace is the G.I. Joe Team's undercover operative. His real name is Thomas S. Bowman, and he was first released as an action figure in 1993. Mace was born in Denver, Colorado.
His primary military specialty is undercover surveillance. His secondary military specialty is intelligence. Mace has spent years undercover, working against Cobra and other criminal factions. He feeds information to fellow "Battle Corps" members, who then make the resulting raids and arrests.
Major Altitude is the G.I. Joe Team's Battle Copter pilot. His real name is Robert D. Owens, and he was born in Rumford, Rhode Island. Major Altitude was first released as an action figure in 1991, as part of the Battle Copters line. He came exclusively with the "Battle Copter" vehicle. He was released again in 1993, as part of a mail-in special called "Terrifying Lasers of Destruction". He was packaged with a Cobra agent, another helicopter pilot, called Interrogator.
Recoil is a 1953 British crime film directed by John Gilling and starring Kieron Moore, Elizabeth Sellars and Edward Underdown.
When thieves rob and murder her jeweller father, Jean Talbot resolves to bring them to justice by posing as a criminal and infiltrating their gang. She builds up evidence against her father's murderer by pretending to be in love with him.
TV Guide called the film "a taut and action-filled programmer."
Bloodline is a 2005 novel written by Kate Cary. It is an unofficial sequel to Bram Stoker's Dracula. Like the original novel, Bloodline is an epistolary novel written entirely in letters, diary entries and news articles. A second novel, titled Bloodline: Reckoning was later released.
Bloodline takes place during World War I. John Shaw, a nineteen-year-old, joins the British Army and is sent to the front lines, in the trenches. He works as a communications officer who listens to German radio feeds and translates what he hears. His regiment commander is a man named Quincey Harker, who is the son of Jonathan Harker and Mina Murray from the original Dracula novel.
Harker is famous for going on raids in the enemy trenches alone at night, and shows several feats of superhuman strength that seem impossible. He is also shown to be cruel to his men. One night a soldier named Private Smith falls asleep on his watch, and Germans invade the trench. As punishment, Harker orders him to be tied to a wagon wheel on no man's land. Private Smith does not die from being shot or shelled, but appears to die of fear.
Bloodline is the eleventh volume in a series of Repairman Jack books written by American author F. Paul Wilson. The book was first published by Gauntlet Press in a signed limited first edition (May 2007) and later as a trade hardcover from Forge (September 2007).
Bloodline is a 1977 novel by Sidney Sheldon.
