WHAT IS FORCE?
Students learn sine wave, to rotate their punch at the last minute and pull the other hand to the belt simultaneously, etc. Grasping the scientifc reasons behind these specifics however, will inform your movements as attacker and defender, thus allowing physics to work more fully on your behalf.
Definitions for Force
Force is a push or pull
Force is the capacity to do work or cause physical change
A force is that which changes or tends to change the state of rest or motion of a body.
Force= Mass times Acceleration (F = ma).
The acceleration (a) of an object is directly proportional to the force (F) applied, and inversely proportional to the object's mass (m). That means that the more force you apply to an object, the greater the acceleration. And, the more mass the object has, the lower the acceleration. So, even if you are a small martial artist, you can produce a lot of force through great acceleration. If you are a large practitioner, although you may not be as agile, your mass will contribute to your ability to generate force.
