if a part of the body moves back and forth
Which mechanical motion creates a back and forth or up and down mechanical motion which could hit or trap you between a moving part and a stationary object?
Reciprocating motion
Does the order of addition of indivitual vectors affect the final resultant vector and why?
The order of addition of individual vectors does not affect the final result. The reason is that "addition is commutative", meaning C=A +B = B + A. The laws of multiplication fro vectors is non-commutative and AxB = - BxA. Multiplication of vectors is non-commutative. Vectors and Reals make up our natural numbers called Quaternions . Given a quaternion A=Ar + Av where Ar is the real part of A and Av is the vector part of A and B=Br +Bv, the product is: AB=(Ar + Av)(Br + Bv)= (ArBr - Av.Bv) + (ArBv + AvBr + AvxBv) If the vectors are perpendicular Av.Bv=0, (the dot '.' denotes the cosine product). If the vectors are parallel AvxBv=0, (the cross 'x' denotes the sine product). Unfortunately quaternions multiplication is not taught in schools. Quaternions simplify algebra, trigonometry and vectors. Quaternions are also the natural numbers of the Universe.
Why does a window left slightly open whistle on a windy day?
While there are a few ways to think about what sound is, for our purposes we will think of it as the rapid back and forth movement of a group of air molecules. What is happening in the case of the window is that the flow of air hitting an edge on the window is unstable. As you can imagine the fluid mechanics involved is quite complicated and quite frankly beyond me. However, the principle is the same as when you generate a sound by blowing on the top edge of an empty bottle. In that case what is happening is that part of the stream of air is quickly flipping back and forth between going over the lip of the bottle and going into the bottle. When it starts going over the lip of the bottle, forces are created the causes it to start going into the bottle. However when it starts going into the bottle, there are forces that are created that cause it to start going over the lip of the bottle. This happens over and over again very quickly. The forces that pull the air stream back and forth are called "negative feedback" forces. All wind instruments use the combination of air flow and negative feedback to generate their sounds. How quickly the flow moves back and forth depends on the dimensions of the cavity, the size of the column of air hitting the edge and the speed of the air flow.
What part of the word commutative means to go back and forth?
Not exactly back and forth. To commute something means "change something for another thing" so commutative means that it can be commuted.

What was the 1st last thing to soon be built yesterday?
I have parts that swing back and forth, back and forth, while part of me stays put could be for a swing

Is 6 times 2 and 4 times 3 part of the commutative property?
No. Or yes if you mean that 6 x 2 = 2 x 6, and 4 x 3 = 3 x 4.
