actionreaction
Hello, buddies!
I read a piece of text, where I found a puzzling interpretation of Newton's third law (F1=F2).
The author gives the following representation: F=Rv(m1m2/l^2)
R  reaction;
m1, m2  masses;
v  velocity of reaction;
l  distance between the two objects.
Please, help me with explanations about the equation, suggestons about its derivation? I will be grateful for every comment.
The formula reminds me of Newton's law of universal gravitation: F=k(m1m2/l^2)
F  force between the masses;
k  gravitational constant;
m1, m2  masses;
l  distance between the centers of the masses.
But what is the reason for replacing k (gravitational constant) with Rv .... any ideas?
It is puzzling matter, this author keeps me thrown in confusion...
