Title: Vector notation
Content: with the members of the standard basis in formula_11. The basis is represented with the unit vectors formula_14, formula_15, and formula_16. A three-dimensional vector v can be specified in the following form, using unit vector notation: Where "v", "v", and "v" are the scalar components of v. Scalar components may be positive or negative; the absolute value of a scalar component is a magnitude. The two polar coordinates of a point in a plane may be considered as a two dimensional vector. Such a "polar vector" consists of a magnitude (or length) and a direction (or angle). The magnitude, typically

Title: Magnitude (mathematics)
Content: in numeric quantities, usually measurements, by a factor of 10—that is, a difference of one digit in the location of the decimal point. Magnitude (mathematics) In mathematics, magnitude is the size of a mathematical object, a property which determines whether the object is larger or smaller than other objects of the same kind. More formally, an object's magnitude is the displayed result of an ordering (or ranking) of the class of objects to which it belongs. The Greeks distinguished between several types of magnitude, including: They proved that the first two could not be the same, or even isomorphic systems

Title: Force
Content: know both the magnitude and the direction of both forces to calculate the result. If both of these pieces of information are not known for each force, the situation is ambiguous. For example, if you know that two people are pulling on the same rope with known magnitudes of force but you do not know which direction either person is pulling, it is impossible to determine what the acceleration of the rope will be. The two people could be pulling against each other as in tug of war or the two people could be pulling in the same direction. In

The Greeks distinguished between several types of magnitude, including: They proved that the first two could not be the same, or even isomorphic systems of magnitude. They did not consider negative magnitudes to be meaningful, and "magnitude" is still chiefly used in contexts in which zero is

Title: Magnitude (mathematics)
Content: the distance of "P" from the origin of that space. The formula for the absolute value of is similar to that for the Euclidean norm of a vector in a 2-dimensional Euclidean space: where the real numbers "a" and "b" are the real part and the imaginary part of "z", respectively. For instance, the modulus of is formula_4. Alternatively, the magnitude of a complex number "z" may be defined as the square root of the product of itself and its complex conjugate, "z", where for any complex number , its complex conjugate is . A Euclidean vector represents the position

Question: Which quantity has direction as well as magnitude?
Answer: Vector quantity
