What the magnitude alone of a vector quantity could be called?
scalar
Why can velocity be negative but nonzero speed is always positive?
speed is a scalar quantity with magnitude only but no direction; velocity is a vector with both magnitude (speed) AND direction, which could be positive or negative
If a car drove a around in a circle would that be constant velocity?
No. Velocity is a 'vector', which means it's a measurement that has both magnitude and direction. The magnitude is what we usually call the 'speed'. For an object moving in a circle, it could have constant speed ... the velocity could have constant magnitude ... but there's no way the whole velocity vector could be constant, because the direction is always changing. Constant velocity is very easy to recognize ... the object is moving at a steady speed, in a straight line.
How do you make a story using vector quantity?
Vector quantity is the measurement of both magnitude and direction of the movement of a medium. If you wanted to make a story using vectory quantity, you could compare it to scalar quantity.
What is the result resultant acceleration?
Acceleration is a vector, meaning each acceleration has both magnitude and direction. The resultant of vectors is basically the net acceleration on the object expressed as a single vector. For example, if there are two vectors each with a magnitude of 2 meters/(seconds squared) acting on an object and these vectors were placed on the x and y axes then you could represent this system of 2 vectors 90 degrees apart each with a magnitude of two meters/(seconds squared) as one vector of 45 degrees with a magnitude of 2 times the square root of 2 meters/(seconds squared).
Which of the following values could possibly be vector magnitudes meaning that combined with a direction they could become vector quanities?

What could describe the magnitude of a vector?
A vector could describe a something physical like a force or velocity or acceleration or torque for example. The units would be part of the magnitude of the vector. For example, the wind is blowing South at 10 mph. The magnitude is 10 miles per hour.
What the magnitude alone of a vector quantity could be called?
scalar
A vector a is along the positive z axis and it's vector product with another vector b is zero then vector b could be?
Vector b would be along the z axis, it could have any magnitude.
A vector always consist of?
A vector always consists of a direction and magnitude. For example, a vector representing the weight of an object that is 35N would be represented as an arrow pointing downward with a magnitude of 35N. You could also represent the weight of 35N as -35N, in which the negative symbol indicates a downward force.
Can a vector have a negative value?
A vector is characterized by a magnitude, direction and sense of direction. If you are referring to the magnitude of a vector, it cannot be negative because of the way the magnitude is calculated. For example, vector F has components Fx and Fy. The magnitude of F is (Fx^2+Fy^2)^(1/2)However, you could see something like -F. What you are really looking at is multiplying a vector, F by -1. What this means is that -F has the same magnitude and line of action as F, but has an opposite direction as F.
How could you represent the speed and direction of a car if you able to measure its position vs time?
If s is the vector which denoted the position at time t, then the vector ds/dt is the required vector. Its magnitude is the car's speed and its direction is the car's.
Why can velocity be negative but nonzero speed is always positive?
speed is a scalar quantity with magnitude only but no direction; velocity is a vector with both magnitude (speed) AND direction, which could be positive or negative
What is a vector measured in?
A vector has magnitude and direction. You can specify the direction with an angle, then the magnitude depends on what you're measuring (force, velocity, etc.) The direction could also be something specific to the quantity measured, like saying the wind is blowing 15 miles per hour to the Northwest.
Can two vectors of unequal magnitude add up to give the zero vector?
No. The vector resultant of addition of vectors is the vector that would connect the tail of the first vector to the head of the last. For any set of vectors to add to the zero vector, the endpoint of the last vector added must be coincident with the start point of the first. Therefore for the sum of only two vectors to have a chance of being the zero vector, the second vector must be in a direction exactly opposite the first. So you can tell that the result of adding the two vectors could only can be zero vector if the two vectors were of two equal magnitude.
Can a vector have 0 component along a line and still have non zero magnitude?
Huh?I have been kicking around your question in my mind for five minutes trying to figure out an answer or a way to edit your question into an unambiguous form, but I'm stumped. I don't know what you mean by "zero component along a line."If you look at the representation of a vector on paper using a Cartesian coordinate system -- in other words, one using x and y axes -- the orthogonal components of the vector are the projections of the vector on the x and y axes. If the vector is parallel to one of the axes, its projection on the other axis will be zero. But the vector will still have a non-zero magnitude. Its entire magnitude will project on only one axis.But a vector must have magnitude AND direction. And if it has zero magnitude, its direction cannot be determined.Still trying to make heads or tails out of your question.......If you draw a random vector on a Cartesian grid, it will have an x component and a y component, which are both projections of the original vector upon the axes. However, it could also be represented by projecting it onto a new set of orthogonal axes -- call them x' and y' -- where the x' axis is oriented to be parallel to the original vector and the y' vector is perpendicular to it. In that case, the x' component will have a magnitude equal to the magnitude of the original vector -- in other words, a non-zero value along a line parallel to the x' axis -- and a zero magnitude in the y' direction.
