Does The direction a vector is drawn in indicate the magnitude of the vector?
No. The two characteristics of a vector ... its magnitude and its direction ... are independent of each other. Either one can change without affecting the other, and neither one tells you any information about the other. On a drawing, the direction of the vector indicates nothing concerning the magnitude. The length of the vector is usually used to indicate its magnitude, on a drawing.
Vector quantity will be described numerically or graphically?
it can be described in both. when graphically, it will be represented by an arrow in the direction of the vector and have the magnitude either written by it or you will have the arrow drawn to scale for the magnitude (length) of the arrow. numerically, you can break it down into its x, y, and z components and put them in from of i, j, and k respectively. ex a vector with x component of 3, y component of 2 and z component of 4 can be written as 3i +2j +4k
When two vectors A and B are drawn from the same point the angle between them is phi If A and B have the same magnitude which value of phi will their vector sum have the same magnitude as A or B?
120 degrees. Go mountaineers!
Is the magnitude of a vector represented by the length of an arrow?
Yes, but the length depends on the scale that we assign.
A vector that is 1 cm long represents a displacement of 5 km how many lilometers are represented by a 3 cm vector drawn to same scale?
if 1 cm is 5km.... 3cm? 5+5+5 ..15km dirrtyy suckas!

What is a characteristic of a correctly drawn vector diagram?
the magnitude and direction of the vector are given.
What is a quantity that has both Magnitude and direction called?
A quantity that has both magnitude and direction often has an arrow drawn over the unit of measurement. This is known as a vector quantity, as opposed to a scalar quantity which has no direction.
What is An arrow drawn to represent the direction and magnitude of an object is referred to as?
There is no such thing as the direction or magnitude of an object. The direction and magnitude of its speed, acceleration, or momemtum, or of the forces on it, are represented by vectors.

What are force calculations?
Calculations with forces. Often these have to be calculated as vectors, i.e., the direction of the force is taken into account. You should do some reading on vector addition; however, the basic idea is that you can think of the vector as an arrow drawn on paper; the length is proportional (in this case) to the force, the direction indicates the direction. A common tool is to separate the vector (the arrow) into horizontal and vertical components. That way, you can easily add two or more vectors. This requires some trigonometry (or the special functions of your calculator, for rectangular-->polar, and polar-->rectangular conversion).Calculations with forces.

How do you subtract vectors?
it depends on the method of subtraction. If the vectors are drawn graphically then you must add the negative of the second vector (same magnitude, different direction) tail to tip with the first vector. If the drawing is to scale, then the resultant vector is the difference. If you are subtracting two vectors <x1, y1> - <x2, y2> then you can subtract them component by component just like scalars. The same rules apply to 3-dimensional vectors

Yes, but the length depends on the scale that we assign.
Why is velocity tangential to the path of a body?
Velocity is a vector; having direction. So, when changing direction constatly to have velocity a tangent can be drawn to the constantly changing path of the object having velocity.
Why is it necessary to use the trig function cosine when working with vectors?
The cosine function is used to determine the x component of the vector. The sine function is used to determine the y component. Consider a vector drawn on an x-y plane with its initial point at (0,0). If L is the magnitude of the vector and theta is the angle from the positive x axis to the vector, then the x component of the vector is L * cos(theta) and the y component is L * sin(theta).
