Simply put, a vector is 2 dimensional.
Think of speed - it is only one dimensional. It is not a vector, it is a scalar. It is measured in a scale, most commonly noticed when inside a vehicle. You are travelling at 100km/h (60mph)
Vectors are 2 dimensional, they have a magnitude and a direction.
Think of velocity, as an arrow - imagine you are travelling at 60 mph in a northerly direction, your arrow would be pointing to the notth, with a magnitude of 60mph, If you were travelling at 60mph in a southerly direction, your velocity vector would be pointing towards the south, the exact opposite of your vector if you were travelling in a northerly direction.
However the speed in these two scenario's, speed not being a vector, remains exactly the same, 60mph.

Is rotation scalar or vector?
Rotation is a vector having a direction and magnitude.
Positive rotation of a vector is?
counterclockwise
Why only cos theta is used in vector functions?
It's not. Cos(Θ) only gives you the x-component of a vector. In order to find its y-component, you also need to use sin(Θ).
What is the meaning of delta in math?
Typically, delta means "change in" in math.
What trig functions is useful for finding the horizontal componet of a resultant vector?
There are no useful ones on the list that follows the question.
Are there any math words that start with V?
vector
Math words that start with V?
vector, vertex, there are probably others
What is puc vectors?
A pUC vector a circular, double stranded DNA molecule normally used for recombinant protein expression. It is not a math vector.
What you the math terms for j?
A unit vector in the positive direction of the y-axis.
What is the difference between regular math addition and vector addition?
Regular Math Addition: 432+53=485 Vector Addition: if u=<a,b> and v=<c,d> then u+v=<a+c,b+d>
How do you do rotation in math?
A vector rotation in math is done on a coordinate plane.2D vectors can be rotated using the cross and dot product.3D vectors are rotated using matrix based quaternion math.
What does gradient mean in math terms?
A vector having coordinate components that are the derived during the solving of a function.
Is it true that all physical quantity which has a direction and a magnitude is a vector?
I think so, yes; that's basically what the concept of a "vector" in physics is all about. (There are also more abstract vectors in math and physics, but something that has a magnitude and a direction would be enough to quality as a vector.)
What is the differentence between calculus and vector calculus?
Hence the reason for why it is called Vector Calculus, Vector Calc. is simply an expansion in the calculus subject are in math. It deals with Taylor's Formula (in calc 2 you learn the taylor polynomial and the taylor series), theorems from Green, Gauss, and Stokes, and much more.
Displacement and velocity are examples of what?
In math and physics, displacement and velocity are examples of vectors. The definition of a vector is that it is quantity that has both direction and magnitude. A vector is represented by an arrow that shows the direction of the quantity and a length which is the magnitude.
How do you relate tangent graph with the math error in calculation of direction of resultant vector?
The tangent function will generate a calculator "math error" if the angle in questin is ±90 degrees. For these angles, the tangent function is not defined.
What kind of math is used in physics?
One uses calculus including differential equations and vector calculus in the undergrad courses which is as far as got.
