vector: Definition, Synonyms from Answers.com
vector n. Mathematics . A quantity, such as velocity, completely specified by a magnitude and a direction
Example of a vector quantity that has a direction but not a magnitude?
A Scalar (ex: mass) has a magnitude but not a direction.
A Vector (ex: velocity) has both a magnitude and a direction.
Can you give any examples of quantities that have a direction but not a magnitude? Are these still called vectors or is there another term for them?
Answer: Sure... bearings have direction but not magnitude, for example, 20 degrees north by east. I wouldn't call them vectors because they're only directions, without magnitude.
Category: Physics
How can you determine whether or not an equation (physics) is a scalar or vector quantity?
For example which are vector quantities?
F(average)*Dt
Sigma of m *r^2
m*absolute value of Dv
Answer: Any thing that has a direction is a vector, that is force, acceleration, velocity. momentum, current, gravitational, electric and magnetic fields. etc. However in many simple problems only one direction is allowed and so vectors can treated as a scalar quantity by using the magnitude or absolute value (which is a scalar) of the vectors. Mass, temperature and energy are true scalars.
r is a vector from the origin to the position and r^2 is the dot product of r's, which is a scalar. dr/dt is velocity which must be a vector. However r dr/dt when which is centripetal force is a cross product of two vectors which is also a vector.

Why cannot we divide two vector quantityies, secondly why cannot a scalar quantity be added to a vector quanti
secondly why cannot a scalar quantity be added to a vector quantity?
Answer: Dividing by a vector wouldn't make sense. A vector has magnitude and direction, so you would be involving a direction in your divisor. When dividing vector by a scalar the scalar only effects the magnitude of the vector.
You can't add a scalar to a vector as the 2 quantities will have different units. You can only add quantities with the same units.
For example you can't add distance to speed. It wouldn't make sense to try and add 2metres to 2metres per second.

Why angular displacement is either scalar or vector quantity?
I am very confused that angular momentum is either scalar quantity or vector quantity
if anyone knows then plz answer this question
It was put up in my entrance exam for non medical
plz answer this question ................i want to know
Answer: Angular displacement is a vector in the sense that it can have two possible directions,called clockwise and anticlockwise.,similarly angular velocity and angular momentum.There are two types of vectors in physics,called Polar and Axial.Polar vectors have a head and a tail while axial vectors don't.Angular quantise are axial because there is an axis of rotation.Angular momentum is an axial vector.

how to make time a vector quantity?
is it possible to make time a vector quantity? if so, what are the possibilities to do that or how would we do that? could this lead to time reversal? please provide good info and please no negative comments. thank you.
Answer: Multiply time by velocity and you will get a distance vector.
3 mph east * 3 hours = 9 miles east.
If you have a graph where one of the variables is time, then you already have the potential for a vector quantity.
Measuring a specific quantity of time forward or backwards gives you magnitude and direction.
Magnitude and direction is the specification of a vector.

Can someone explain the difference between a scalar and vector quantity?
I need to know what the difference is between them to answer these questions:
Which of the following is NOT a vector quantity?
a.) 2 miles per hour
b.) 2 pounds
c.) 2 newtons
d.) 2 kilometers per hour east
e.) 2 dynes
Which of the following is NOT a scalar quantity?
a.) 2 miles per hour
b.) 2 kilograms
c.) 2 apples
d.) 2 ounces
e.) 2 liters
Im not looking for you to answer the questions as I already know the answers[ a.) and d.) - from the book] but I need to know the difference between a scalar and vector quantity so I can answer them myself. The book is simply a workbook and has no explanations.
Answer: A scalar is just a number, and a vector is a number with a direction involved.
In the first question, pounds, newtons, and dynes are all *forces*. A force can't exist as just a number; force has to be directed somewhere. 2 kilometers/hour east gives you a number and a direction. The answer a) is just a speed. You can know something is traveling 2 miles/hr without knowing what direction it's traveling. You can't say something is simply exerting 2 pounds of force; it has to be exerting it on something else.
In the second question, we've already said that 2 miles per hour was a scalar. 2 apples is obviously directionless. 2 kilograms and 2 liters just tell you how much of something you have. 2 ounces here must mean ounces in a pound rather than fluid ounces. So these are a weight, which is again a force and has to be directed somewhere.

Can we find a vector quantity that has a magnitude of zero,but components are different from zero?
Can you explain it for me..
thanks!
Answer: If you are talking of only one vector quantity, the reverse could be "partially" true. There can be a vector quantity that has "a" component equal to zero, but only one component. For instance, you can take any vector and the component of such vector along an axis that is perpendicular ( _I_ ) to its line of action is zero.
But your question is the reverse. You want a "vector quantity that has a magnitude of zero" and has components equal to something. The answer is "NO" and the other answer is "INDEFINITE"
1) NO------you can't chip off something from nothing. (that is philosophical). In Physics, it could be like saying
R^2 = (Rx)^2 + (Ry)^2....will become--> 0^2 =( Rx)^2 + (Ry)^2 (hehe, you can put this to a question, seems you can't form a triangle with these as sides)
2) INDEFINITE ------ consider the diagram below
..................F2
.................../\
....................I
.F1...............I..O
....<--------------I------------>F3
....................I
....................I
...................\/.F4
If all forces F1, F2, F3 and F4 are equal, the Resultant is Zero. You can arrange an "indefinite" number of pairs of equally opposed forces all acting at point "O" and the Resultant will still be zero.
This means:
You could have a vector V, which is zero,
here it is---------->* V ....(a point, but a point is not a vector???)
And the components are Vax = - 2, Vbx = +2 , Vay = - 2 and Vby = +2 which when added will all equate to ZERO. And you can still add as many components you wanted so long as they are in pairs and opposed to its other "infinite" in quantity.
When we say, in conditions of equilibrium that the summation of all components on all axis is zero, we meant that there is no value anymore that is unbalanced in the system of forces being considered. This is done by first taking the resultant of all the forces acting, and then let that Resultant act on the reversed direction, in order to have equilibrium.
Wheww..., girl, that's the philosophy of it.(SPLENDED QUESTION you got here. I admire Creative minds.)

Is electromotive force a vector quantity?
On a cathode ray oscilloscope, the output waveform of an ac generator looks like a sine/cosine graph. The ups and downs represent the change in voltage, right? But why does voltage change? Isnt it the current that changes?
And thus, since voltage/e.m.f can be negative (since it can drive the current in two opposite directions), does it mean that e.m.f is a vector quantity?
Answer: Well, the fact that does matter is this... An ac generator not only gives an alternating current, but even the voltage varies periodically with time. That's the reason why you get a sine/cosine wave as output.
Regarding your second question, voltage/emf isn't negative in the pure sense of the word. for example, in an inductor, the magnitude of induced emf is given by e = -Ldi/dt where the negative sign indicates that the direction of the induced emf is opposite to the direction of the applied voltage, or to put it simply, the induced emf opposes the cause (as given by Lenz's Law). The magnitude of the voltage/emf is always positive. The negative sign only indicates the direction. And, it implies that emf is a Vector quantity.
