Explain vectors
Vectors: a quantity that has a size as well as direction is known a vector. So, for example, the wind blows with some speed and in some direction. So the wind velocity is a vector.
If we choose axes, then a vector is fixed by its components along those axes.
In one dimension, a vector has only one component (call it the x-component).
In two dimensions, a vector has both x and y components.
In three dimensions, the components are along the x,y,z axes.
