Can F_1,2 Be Defined Using r-hat_2,1 Instead of r-hat_1,2?

In summary, the concept of vector direction involves understanding the magnitude and direction of a vector in a coordinate system. This includes calculating the angle between the vector and the axes, as well as determining the positive or negative direction of the vector. It is important to note that vector direction is different from vector position, which refers to the location of the vector in space. Understanding vector direction is crucial in various fields such as physics, engineering, and mathematics, as it allows for accurate calculations and predictions of motion and forces.

In this example (https://imgur.com/a/pTFIt) could i define F_1,2 in terms of r-hat_2,1 instead of r-hat_1,2?

Sure, why not? As long as you take into account that they have opposite directions.
