In addition to field geology training, the astronauts also participated in training for the use of the spacesuits, adapting to the reduced lunar gravity, landing and recovery post-mission, sample collecting, maneuvering in the Lunar Roving Vehicle, survival training and preparation for other technical aspects of the mission.

This centripetal force is not a third force applied to the ball, but rather must be provided by the net force on the ball resulting from vector addition of the normal force and the force of gravity.

The resultant or net force on the ball found by vector addition of the normal force exerted by the road and vertical force due to gravity must equal the centripetal force dictated by the need to travel a circular path.

In addition, ordinary matter is not strong enough to support a hollow shape of planetary size against the force of gravity ; a planet-sized hollow shell with the known, observed thickness of the Earth's crust, would not be able to achieve hydrostatic equilibrium with its own mass and would collapse.

In addition, by choosing to move along curved paths while leaning their bodies radially and flexing their knees, skaters can use gravity to control and increase their momentum.

The theory is successful in that one mode will always correspond to a graviton, the messenger particle of gravity ; however, the price to pay are unusual features such as six extra dimensions of space in addition to the usual three for space and one for time.

He argued for an attracting principle of gravitation in Micrographia of 1665, in a 1666 Royal Society lecture " On gravity ", and again in 1674, when he published his ideas about the " System of the World " in somewhat developed form, as an addition to " An Attempt to Prove the Motion of the Earth from Observations ".

In addition, kerosene-based engines generally provide higher thrust, which is important for takeoff, reducing gravity drag.

In addition the tailplane helps adjust for changes in the center of lift, and center of gravity caused by changes in speed and attitude, or when fuel is burned off, or when cargo or payload is dropped from the aircraft.

This twice-per-second adjustment counters the effect of gravity as the telescope moves, in addition to other environmental effects that can affect the mirror shape.

The addition of Epsom salts to attain the desired specific gravity may have a therapeutic effect on hypertonic muscles.

In addition there are subtle references to Isaac Newton and the law of gravity, perhaps alluding to Kracklite's own inability to escape the physical laws of mortality.

In addition to the gravity and cosmic rods, Ted created the cosmic staff used by his son, Jack, and the cosmic converter belt worn by his JSA teammates, the Star-Spangled Kid and Stargirl.

In addition to atmospheric pressure, the density of the liquid, and gravity, the maximum height of the crest is limited by the vapour pressure of the liquid.

This enables the marker to have a higher rate of fire than a gravity feed without the addition of a battery operated loader ( at the cost of air efficiency ).

Body fluids shift upward in weightlessness, away from the lower extremities, and LBNP, in addition to gathering medical data, serves to counteract this effect and helps astronauts more easily readapt to gravity upon their return to Earth.

Also, since the Sun's gravity varies as whereas the Poynting – Robertson force varies as, the Poynting – Robertson effect also gets relatively stronger as the object approaches the Sun, which tends to reduce the eccentricity of the object's orbit in addition to dragging it in.

In addition, there are less dense felsic rocks in the western shore of the lake, which can contribute to the gravity low.

In addition the 2-10-2, like the 2-6-2, had its main rod connected to the third axle, very near to the centre of gravity, which created a violent nosing action when operating at speed.

Unlike later Requiems, it includes polyphonic settings only of the Introit, Kyrie, Tract, Offertory, Sanctus, Agnus, and Communion ( the Dies Irae, often the center of gravity in more recent Requiems, was a later addition ).

They usually create a downward pressure which counters the unbalanced moment due to the airplane's center of gravity not being located exactly on the resulting centre of pressure, which in addition to the lift generated by the main wing includes the effects of drag and engine thrust.

This top layer has gravity acting downward in addition to the water molecules below pulling down the upper molecules.

In addition to all firearms, the term deadly weapon encompasses knives of a certain length ( usually three inches or longer, depending on jurisdiction ), and in many jurisdictions includes the switchblade, gravity knife, ballistic knife, stiletto, sword, dagger, blackjack, brass knuckles, nunchaku ( fighting sticks ), shuriken ( throwing stars ), among other weapons.

The addition of gravity to the story leads to a considerably richer variety of phenomena.

Warren and White each carried, in addition to their own weapons and ammo, a box of ammo for the ROK's machine gun.

There's another addition to the Stevens line, the pump-action Model 77 in ( under $75 ), which you may or may not consider a kid's gun ; ;

The Sheridan's gun was a low-velocity weapon suitable in the assault role, but with the addition of the Shillelagh missile could double in the anti-tank role as well.

In addition, due to the development of body armor, support personnel required a compact weapon with more penetration than the traditional submachine gun, leading to the development of the personal defense weapon, or PDW, which uses rounds that have better ballistics than simple pistol rounds but less power and range than full rifle rounds.

It was not a gun itself, but an addition to the soldiers ' spears.

In addition to these critical items, the equipment used to assemble the cartridge also has an effect on its uniformity / consistency and optimal shape / size ; dies used to size the cartridges can be matched to the chamber of a given gun.

In addition, the long barrel of a long gun usually provides a longer sight plane for iron sights, providing the user with more precision when aiming.

In addition to serving as backup guns, revolvers still fill the specialized niche role as a shield gun ; law enforcement personnel using a " bulletproof " ballistic shield ( Gun shield ) sometimes opt for a revolver instead of a self-loading pistol, because the slide of a pistol may strike the front of the shield when fired.

In addition to the problems presented by aluminum construction, the Sheridan had one glaring defect that no other armored vehicle possessed ; it fired caseless 152mm main gun rounds.

In addition to production of pre-war designs they developed and produced during the war the Błyskawica submachine gun, Bechowiec, KIS and Polski Sten machine pistols as well as the filipinka and sidolówka hand grenades.

In addition, he had mentioned a gun count and compiled a hit list of individuals he wished to target ( although no overall plan detailing how he intended to attack targets he had specified was ever posted upon the site ).

Reflecting back to very early in the film when he's reputed to be a gun fighter ( aka Pudgy McCabe ) who shot someone in a card game, one of the hired killers ( the third gunman ) after hearing the story, with the addition that the gun was a derringer, proclaims that McCabe has never killed anyone in his life.

In addition thirteen 6-inch ( 15 cm ) gun installations were constructed around Wellington, along the Makara coast, and at entrances to the Marlborough Sounds.

In addition to twin screw propellers, it was originally designed to mount a 12-inch muzzle loading gun on a revolving pedestal.

In addition to farming and related industries, Jamestown was home to a gun factory, which manufactured a sturdy and accurate muzzle-loading gun known as the " Jamestown Rifle ," the mainstay of Jamestown's industry through the latter half of the 19th century and a highly prized collectible among gun enthusiasts today.

In addition to the pig iron, cannon balls were manufactured at some of the local furnaces and shipped out, along with gun powder from a local gun powder plant, for use by the Confederacy.

Adding to the airborne units ' firepower was the fact that ¼ of them jumped with a MP 40 submachine gun, often carried in addition to a bolt-action Karabiner 98k rifle.

He also notes that the gun is somewhat lesser than the bow, since at that time guns were not very accurate at ranges any longer than point-blank in addition to the disadvantage of being unable to see the bullet and adjust your aim as you would with a bow.

In December 1914, French pilot Roland Garros approached Saulnier to arrange for this device to be installed on his aeroplane but it was not until March 1915 that he took to the air with a forward-firing Hotchkiss 8 mm (. 323 in ) machine gun mounted on his Morane-Saulnier Type L. In addition to the armoured blades, Garros's mechanic, Jules Hue, attached deflector wedges to the blades.

A first-class arsenal, which can furnish the material and equipment of a large army, contains a laboratory, gun and carriage factories, small-arms ammunition, small-arms, harness, saddlery tent and powder factories, and a powder factory ; in addition it must possess great store-houses.
