Force

Centripetal and Centrifugal Force

Two other forces that come into play during the practice of Taekwondo are centripetal and centrifugal force. Centripetal force is the force that draws objects into a spinning whirlpool. Centrifugal force is the force that throws objects off a spinning top. These forces come into play when using spinning kicks and releases that use a spinning motion.

Potential and Kinetic Energy 

Potential energy is energy at rest; it is stored and available for use. Kinetic energy is energy in motion; it is consumed as it is used. When throwing an opponent, you use your kinetic energy to lift the opponent off the floor against gravity. At the peak of the throw, potential energy is stored within the opponent. To complete the throw, you release the opponent and the opponent's potential energy changes to kinetic energy as gravity forces the opponent to the floor.
