Momentum
hello

In Judo and Jujitsu there is a corolation between Issac Newton's First Law of Motion, not the Third Law.
"Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it".
The "application" of a Judo or Jujitsu technique is the "external force" applied to the motion of your opponent (F = ma).
F = Jujitsu
ma = fly through the air; land on your head and break your neck.
What is the relation between Physics and Martial Arts. Maybe there exist some fine bond between them, but the wat is it?
