what is a vector quantity?

Answer 1

a vector is an function or constant which has both direction and magnitude.

Answer 2

A vector quantity is a quantity that has both magnitude and direction. Velocity, acceleration and momentum are the example.
Let me give you an example, imagine that you are in a car, your car travel at a speed of 60km/h or 60 miles/hour. It goes foward and not reversing. The vector quantity is velocity. the magnitude is 60 km/h and the direction is to the front. So, find other example for acceleration an momentum, figure it out. Hope, this will help you.

Answer 3

Any physical quantity that has both magnitude (size) and direction, such as velocity, acceleration, or force, as distinct from a scalar quantity such as speed, density, or mass, which has magnitude but no direction. A vector is represented either geometrically by an arrow whose length corresponds to its magnitude and points in an appropriate direction, or by two or three numbers representing the magnitude of its components. Vectors can be added graphically by constructing a parallelogram of vectors (such as the parallelogram of forces commonly employed in physics and engineering). This will give a resultant vector.

The position vector of a point A(x,y) represents the move from the origin to A, that is a translation. A free vector has magnitude and direction but no fixed position in space.

If two forces p and q are acting on a body at A, then the parallelogram of forces is drawn to determine the resultant force and direction r. p, q, and r are vectors. In technical writing, a vector is denoted by bold type, underlined, or overlined

Answer 4

A vector quantity, or a spacial vector is one that has both magnitude and direction. Eg. force, velocity, displacement are specified by both their magnitude and the direction in which they are applied. Vectors usually have an arrow above their symbol to denote that they are vectors.

Answer 5

A vector quantity is something that requires both a magnitude and a direction. Speed tells you how fast you are going, but without direction, you can't tell how far you will be after a given time. Velocity is speed and direction. With a velocity, I can tell you where you will be after a given period of time.

Answer 6

The school definition is something that has magnitude and direction, but its probably more useful and general to use vector to describe a set of measurements that need more than one scalar (simple number) to specify it.

For example, in analysing oscillations you might describe a state by position and velocity (perhaps in polar coordinates), and the classic way of assigning a distance (root of sum of squares of components) might be inappropriate, and in some cases any idea of "distance" and "magnitude" of the vector might be inappropriate.

This then sets the scene for higher order "tensor" entities.

Answer 7

it is a quantity which has both a magnitude and a direction.

for example ... force, velocity, acceleration

a vector quantity may be positive or negative

Answer 8

It has direction and quantity, i.e 5metrs per second in a northerly direction.

Some others:

Space
Velocity
Acceleration

Answer 9

Is it not the amount of new vauxhalls on a dealers forecourt?
