One way of representing a vector is to list its x,y, and z components. Something like v = <1,2,3> m/s. Of course there are many ways to represent a vector.. There is a thing called vector addition.

Well, here is the key to vector addition: Every vector can be broken into two vectors. The same can be done with scalars, its just not usually very useful. For example, I can break up 3 as 1+2.

To achieve the prefix sum, we add the output of each Vector addition to itself. The result shifts by a factor of two on each new summation to take into account previously summed fields. Here’s a ...

From the vector addition of forces. F e /F g = tan(θ) F e = F g tan(θ) Coulomb’s law is. F e = k c (qq / r 2) where k c = 9 x 10 9 N m 2 /C 2 Therefore. k c (qq / r 2) = mg tan(θ) In this problem we ...

Higher; Geometric vectors Geometric vectors. Vectors describe movement with both direction and magnitude. They can be added or subtracted to produce resultant vectors.
