Question by blackbelt08ninja@rocketmail.com: I’m doing a science project about karate. ?
I want to do something about physics and karate, not breaking. I was thinking something about kicks, punches, etc.
Could I get some ideas for experimental questions? 9th grade

Best answer:

Answer by Radon
you should do a karate reverse punch power vs. a boxing style straight punch power

  1. Yes i take Jiu-Jitsu but i think i can answer this.

    You can have questions about Deflection which is how much for example the rib cage is pushed in after a Martial arts punch.

    You can measure the Velocity/Speed of these kicks or punches

    And different areas in the body that can be easily adapted to make some one tap out through a submission.

    You can also measure the amount of Weight/Force going into these Punches or kicks and measure recoil.

  2. Here’s an article that will hopefully inspire/interest you then:


  3. For the testing of the physics of mainly static structures:
    You could experiment with testing the relationship between mass, body structure and balance (over the centre point) by a candidate assuming different Karate stances. Then the examiner pushing and pulling in various ways to test the strengths and weaknesses of balance that characterize the stance. Stances vary depending on purpose and change throughout the variables of a fight. See where the structure can be changed by an opponent to take sufficient mass away from the stance’s centre and supporting foot placement to off-balance and perhaps cause the subject to fall.

    For the testing of the physics of mainly moving structures:
    Test also for the strengths and weaknesses of moving Karate structures, how easy and long a distance can the subject move from different stances, how easily can they turn sideways or fully around, how effective is a ‘landing’ from a movement. How much control do certain structures provide in comparison to others (set up measurement parameters and do up a table).

    For the testing of the physics of leverage and impacts:
    Impact and leverage can be tested by striking a heavy bag using different strikes while maintaining a set speed and action of delivery (not easy to be consistent here). Force equals mass times velocity.

    The aim of Karate in its use of physics (objective of the process):
    The purpose of Karate is to inflict sufficient damage on an aggressor to prevent further attacks and by doing so maintain one’s safety. As it is not necessarily the measure of the power of a blow that decides its effectiveness, but primarily the anatomy of the target zone selected. It would be difficult to test and measure this aspect of the physics of Karate. It is of no use to know a crane’s ability to pick up heavy weights, if it is not connecting up with or into the object that it must lift (work purpose). The obvious physics flows into the less easily measurable field of medicine and trauma. There is data already available on the known usual effects on the body, consciousness and life/death of a subject in relation to the variables of type of strike, method of delivery and target zone. Karate is taught is two parallel complimentary paths or arts, they can be termed, for example: Cause and effect, delivery and result, combat and medicine, or trauma and healing. Refer to your sensei.

  4. hehe i just opened this video as i logged into answers and saw your question
    i think it will have some inspiration for your project :D
    it is about the science behind mixed martial arts
    good luck!

  5. there are only so many ways you can kick and punch. some styles use a slightly different ver, there not wrong just different. they each have there pro’s and con’s
    they also have different ways of blocking.
    some block with hips and shoulder squared other to the side.

    you also have the stances. long, short, deep, standing up, narrow, wide each adds different aspects to a strike.

    one aspect.
    The range of your strike depends on your stance. The longer your stance the further you will be able to move. Hence the shorter your stance the less distance you will be able to cover.
    A wide stance is used for evasion an narrow stance is more of a linear type attack.

  6. geez that is a really tough project, have you considered something else?! when i was in the 9th grade (two years ago lol, gosh i feel old saying “in the 9th grade”)

    i did a project like that with a swing, ketetic energy and velocity blah blah blah, much easier “what goes up must go down and will go down at the same speed no matter the weight, asuming the shape is the same”

    anyway for martial arts you need to consider the biology, how the muscles work and how that affects speed, and when the punch would have to stop of course, that is affected by a number of different aspects of the human body
