vector
In mathematics, physics, and engineering, a Euclidean vector (sometimes called a geometric or spatial vector, or—as here—simply a vector) is a geometric object that has magnitude (or length) and direction. Vectors can be added to other vectors according to vector algebra. A Euclidean vector is frequently represented by a line segment with a definite direction, or graphically as an arrow, connecting an initial point A with a terminal point B, and denoted by
A
B
→
.
{\displaystyle {\overrightarrow {AB}}.}
A vector is what is needed to "carry" the point A to the point B; the Latin word vector means "carrier". It was first used by 18th century astronomers investigating planet rotation around the Sun. The magnitude of the vector is the distance between the two points and the direction refers to the direction of displacement from A to B. Many algebraic operations on real numbers such as addition, subtraction, multiplication, and negation have close analogues for vectors, operations which obey the familiar algebraic laws of commutativity, associativity, and distributivity. These operations and associated laws qualify Euclidean vectors as an example of the more generalized concept of vectors defined simply as elements of a vector space.
Vectors play an important role in physics: the velocity and acceleration of a moving object and the forces acting on it can all be described with vectors. Many other physical quantities can be usefully thought of as vectors. Although most of them do not represent distances (except, for example, position or displacement), their magnitude and direction can still be represented by the length and direction of an arrow. The mathematical representation of a physical vector depends on the coordinate system used to describe it. Other vector-like objects that describe physical quantities and transform in a similar way under changes of the coordinate system include pseudovectors and tensors.
Last week I ordered a new Kriss Vector CRB20 in .45ACP and it has arrived.
After unboxing it I added the Vortex Strikefire II and Fab Defense collapsible vertical grip. Then I loaded up some SMG Tactical 25 round magazines with different types of 230gr FMJ for a break in and evaluation at the...
I have an Alpine White Vector pistol that I’d like to sell or trade. Fired about 300 rounds and now I’m looking for another project to start.
Items included with the firearm are as follows:
TLR-1 NOT included
Factory hard case
Factory 1x 17 round Glock OEM magazine
Factory cleaning brush...
I have a Kriss vector 9mm carbine enhanced FDE for sale. I have 50rds through this rifle. Rifle shoots great and lots of fun and very accurate. $1400 obo. I’m also looking for a Ruger RPR in 6.5 creedmoor or 6 creedmoor.
No longer for sale here. Putting up for consignment.
I'm selling a 5.56mm Vector V93 bought new by me about 10 years ago. Roughly 600 rounds fired with no issues at all. Claw marks and a little light finish wear around the ejection port evident, but otherwise in great condition.
$950...
I am selling my KRISS Vector 9mm pistol with stabilizing brace! I have put about 5 boxes of 9mm down range with this gun. I have many 9mm sbr’s and don’t shoot this pistol. I am looking to buy a Percision rifle from a friend and need money to put towards that. In excellent like new condition. I...
Something for your LIGHT and DARK sides. Kriss Vector in Alpine White and Vader Black. Both are chambered in .45 ACP, both have pistol braces and both are ready to twist on that .45 suppressor. Guaranteed to shoot better than a storm trooper.
Vader Black is on consignment, it's lightly used...
Î Hey there
New to the forum
Selling a CA compliant Vector
Would be a great project to modify
4 10 round Glock mags
200 rounds shot
.45 acp
Super Accurate
Light Surface scratches
$1000 O.B.O.
Willing to meet at any licensed FFL in the greater Portland area
Thanks
Up for sale are two very awesome firearms. The first is my Sig Sauer MCX with an m4-72 muzzle brake. It will include two magpul pmags. This rifle has virtually no recoil what so ever and has already gone through the mandatory BCG recall so it has a brand new bolt carrier group freshly installed...
