The laws of physics
Before explaining the dynamics of the different martial arts,
it is important to first understand the physics that makes it
happen. By understanding the physics behind martial arts you
will be able to determined whether or not a certain type of
punch, kick, grab or throw are more effective. You will also
be able to tell if someone is truly a master verse a fraud.

A list of physics concepts that applies to material arts:
Momentum= mass(weight) X velocity(speed)
Force= mass X acceleration
Torque= lever arm X force
Impulse= force X time
Work= force X distance
Power= work or Torque X w(angular velocity)
time
Kinetic Energy= mass X velocity^(½)

Newton's 3rd Law: Every force has a equal and opposite reaction.
