what are vectors .................
Answers
Answer:
vector is an object that has both a magnitude and a direction. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. ... Two examples of vectors are those that represent force and velocity.

Answer and Explanation:
Most quantities with which you are probably familiar are represented by single numbers: 15 kilograms, or 25.63 seconds, for instance. Such quantities are known as scalar quantities or simply scalars.
However, some quantities have both a size and direction and thus require two or more numbers to specify completely. Such quantities are known as vector quantities or vectors.
For instance, while the speed of an object is simply its rate of motion,(18km/h), an object's velocity reflects not just its rate of motion but also the direction of its motion (18km/h southwest).). As such, speed is a scalar quantity while velocity is a vector quantity. Other vector quantities include force, displacement, and electric field.
Many important physical and mathematical quantities are vectors, and the analysis of generalized vectors and their properties (a subject known as linear algebra) forms part of the core of modern mathematics.
Mathematically, a directed line segment is called a vector. Or, in other words, a line segment with a specified magnitude and direction is called a vector.
