In karate it is called a kata. It is a teaching method that has been used for many centuries.
hit your opponent before they hit you
The definition of karate is to defend oneself without the use of weapons by striking sensitive areas on an opponent's body with the hands, elbows, knees, or feet.
The main difference are the rules. In boxing, only your hands may be used to score points. In karate as a sport, hands and feet can be used to hit the opponent.
The name will depend upon the martial art. In karate it is called a kata. Other arts use the word form or poomse for a sequence.
A karate bow is used to show respect to your teacher (sensai) and elders. We say it osu. A karate bow is also done before the start and end of class, a bout or kata.
While both of them are quite effective martial arts, karate is by its nature more deadly. Judo was derived from Jujitsu. It was designed to be a sport and used in competition. As such it was intended to be 'safe' to the practitioners and not deadly. Karate was never intended for competition, but is designed to be effective and take the opponent out of action.
Karate (Sorry, don't know who created it.)
When you do an illegal technique during kumite or hit to intentionally injure the opponent, you are given a penalty. Penalty can be in the form of extra points given to your opponent. If you get more penalties than the threshold, you can also be disqualified or banned from taking part in the championships.
Fights are not always predictable in the way they turn out, and sometimes the element of surprise is more important than either the skills or weapons which are brought to the fight; that said, the probability is that a karate master can defeat an opponent who is armed with a baseball bat.
You bow in karate to show respect. You bow to your partner or opponent before you spar or train. You bow when entering or exiting the training area to show respect for it. And you bow to your instructor.
The cry is called the 'kia.' It is less of a cry than a sound. It is to be done from the diaphragm and helps focus energy. It can also have an affect on the opponent, and make them think twice about attacking.
