Types of Force

 

Muscular Force

Muscles operate by contraction, so when a muscle pulls a body part in one direction, for the part to return to its original position, another muscle must pull it back. No one muscle in the body may generate the force required to deliver an effective blow. All the muscles of the body must act in concert to generate the required force.

Gravity

All objects exert an attraction on all other objects. The force of that attraction is proportional to the mass of the object that attracts. The attractive force of the earth is called gravity. Since gravity always exists and it is predictable, it is useful in combat. You may not be able to move a larger opponent horizontally and you certainly may not move the opponent vertically, but you may use gravity to cause the opponent to fall by causing the opponent to lose balance. This may be accomplished by pushing when the opponent pulls or vice versa.
