By an arrow, a vector. Velocity is a vector quantity that must have both magnitude (speed) and direction (bearing).
Vectors can be represented graphically in a three dimensional framework (x,y,z) or width, breath and depth from a zero origin.
-2a
They can be represented by a line made with a #2 pencil. The length of the line is made proportional to the magnitude of the vector, and some kind of identifying mark is made on or near one end of the line to show the direction of the vector.
Angular acceleration is the trate of change of angular velocity, often represented by the letter alpha.
The product of mass and velocity of a body is the 'motion quantity' or'linear momentum' of the body. It is a vector quantity, normally represented by P.P = m∙v
Velocity is the slope of the line on a D-t graph
Vectors can be represented graphically in a three dimensional framework (x,y,z) or width, breath and depth from a zero origin.
a vector quantity is represented graphically, by a directed straight-line segment. let us consider an example. suppose a bus is moving towards east with a velocity of 50km/hr. To represent velocity of the bus, we first indicate east-west and north-south direction on the paper.Then we can easily represent vectors.

displacement or distance
Velocity.
Velocity's' symbol is represented by a simple: "V".
Vectors can be represented graphically in a three dimensional framework (x,y,z) or width, breath and depth from a zero origin.
Displacement
A vector is represented graphically as an arrow. The direction indicates the direction, the length is proportional to the magnitude of the vector. Note that it is difficult to accurately represent vectors of 3 or more dimensions on a 2-dimensional sheet of paper.
If you call it "velocity" then you have to tell what direction it points.If you only tell how fast it is but you don't tell the direction, then it's "speed", not velocity.
A perfectly elastic demand is represented on the traditional supply and demand graph with a straight horizontal line. An elastic demand that is not perfect would be represented as any line with a slope between 0 and -1.
