Which is a vector quantity?

1) distance is measured in a particular direction. the vector woudl be displacement\n\n2) speed assumes a direction, vector would be velocity\n\n3) power is a unit of energy work\n\n4) force is a vector as you need to say how hard and which way

Newtons is the unit for measure of force

I'm not sure I understand the question, but if you want to translate the vector from its current position to the origin, then just add (4,-5) to its beginning and end points.\n The vector will now be pointing from the origin to (6,1).\nHope this helps.

Velocity is a vector (basically something that has direction and speed) whereas speed it just a magnitude expressed in terms of its absolute value.

D = M/V\n\nDensity= Mass/Volume

well vectors are just a short way of writing 3 different numbers together. in most cases, they actually have meaning, but sometimes they dont. \nso if you just think about it lik 3 separate equations put together, then it should be a lot easier.\n\nexample:\n(x=5, y=2, z=4) + (x=1, y=9, z=6)\nso to do this, you just do each of the equations separately.\nx = 5+1 = 6\ny = 2+9 = 11\nz = 4+6 = 10\nso the answer is (x=6, y=11, z=10)\n\nso sometimes, vectors are drawn out. using the cartesian plane. in this case, you just have to split up the vectors into their 2 parts and then add their components. \n\nanywayz, I hope this helps. ask me if you need more help or whatever. laterz

The simple answer is that the vector sum of the forces acting on an object must be zero if the object is to remain in "equilibrium" or in other words to have constant velocity.

Without a little more context I can't say for sure but, most likely, it's just another way of asking for the vector sum. That's the one vector that is equivalent to adding up the directions and magnitudes of all other vectors in the problem.

Weight is the amount of force on an object and mass is the amount of matter in that object

In what domain? \nWith what force?\nWith what resistances?

Vector problems involve understanding the concept of having a magnitude and direction.\nVectors are just combinations of certain magnitudes in certain directions\n\nEx: F= 2i + 4j + 3k ( this is a force vector which have 3 components in x,y,z plane)\n\nthe most three important operations on vectors are :\nDOT product :\nF . G = (fx,fy).(gx,gy)= fxgx+fygy \nnote that (F.G) is JUST a number \nwe can also define the dot product as :\nF.G= |f||g|cos(theta) .. where (theta) is the angle between the two vectors\n\nthe other product is the Cross Product\nwhich says that F(X)G= |f||g|sin(theta) n. note that the cross product gives a vector perpendicular to the place of the two vectors which contain F and G\n\nthe thirs important rule is that \n|f|=SquareRootOF(fx^2+fy^2+fz^2)\n\nthese are fundementals!

The magnitude of a force is measured in newtons(N)

Velocity is a vector - this means that it has a direction. Speed is a scalar, i.e. just a number.\n\nTo illustrate, let's say I'm travelling in a spaceship to the moon. My speed is 50,000 mph. My velocity is 50,000 mph towards the moon.\n\nIf there is no direction given, it's not a velocity.

I don't see how components are necessary.  \n\n"r" and "v" are just shorthand for r(t) and v(t), assuming we are looking at position (r) and velocity (v) as time varying "vectors".  And v(t) is just the time derivative of r(t) (by DEFINITION), that is, v(t) is DEFINED as r'(t).\n\nSo there isn't any actual CONTENT in expanding them into components. We are just choosing different ways to symbolize the quantities involved and there isn't anything to prove.

Seems more like a vector analysis question to me.
