Mastering a quick, powerful punch is fundamental to becoming a good karate master. It starts with perfecting your form and using your whole body, not just your arm, to generate force.

E is energy, m is mass, and c is the speed of light in a vacuum. Since then, E=mc2 has become one of the most famous equations in the world. Even people with no background in physics have at least heard of the equation and are aware of its prodigious influence on the world we live in.

This equation is under Physics. Physics is a branch of Science, so we can say it is a scientific equation. But, I think, it can also be called a mathematical equation as for the fact that Math is used for the derivation of this equation. Physics makes use of Math concepts.

An equation derived by the twentieth-century physicist Albert Einstein's theory of relativity says that E (energy) = M (mass) times C (speed) squared. This means that to generate the most energy (power) we need to get as much weight (mass) moving as quickly as possible.

Using correct form not only allows you to strike with the weight (mass) of the entire body, but using proper connection allows you to move the body as a unit, which makes the strikes faster, generating more power.

E = mc2 is the world’s most famous equation—a mathematical formula with the power to transcend the barriers of language and culture.

Sports physiology describes this concept as 'connection' in the martial arts we call it Chi" or 'Ki'.

Ki () meaning is energy or spirit.


It is true that bigger stronger people can strike harder than smaller, weaker people based on their weight, but if the smaller person is faster the scale will be more balanced. If the parties are close to the same weight, the striker with better form will hit harder than the stronger one, as have the same relative mass. Plus as time goes on, strength tends to fade more quickly than form, meaning the better trained fighter will hit harder for longer.
But, a punch requires several forces to accelerate and decelerate from different areas simultaneously.
The force equation for a simple linear acceleration is F=MA.
The force equation for punching is a good method more COMPLICATED than it.

Since 1978, I always try to mention that the concepts behind techniques are the "real" karate martial art.

Body alignment, balancing, stability centre of gravity, rotational kinetic energy, force, self confidence, will power, body mass, focusing, right technique and high speed, impact tension, etc were the most important thing.  These in combination realize (visible form) the concepts that are the basic for all techniques of powerful KARATE.

Learning how to aim correctly and punch within range will give your punches more speed, and you can build strength using training techniques that build your muscles the right way.

A properly executed punch comes from far more then arms.
A punch パンチングまたはパンチは is a striking blow with the closed fist. It is used in some martial arts and combat sports, most notably boxing where it is the only type of offensive technique allowed.

It comes all the way from your foot (pressing down on the ground), through your leg muscles, through body rotation, through hip roll over, and, finally, thought your arm. Therefore the way you are standing on the ground firmly is important.

But it is also how you use all those muscles.

Many people power loss by tensing up all the way to their target. With relatively relaxed muscles on the way to the target, tensing up just before impact, you save more energy for the impact.

Many hand techniques require one to make a fist and it is important that it is done correctly.  


·         The fingers should be curled tightly into the palm

·         The thumb lays tightly on top of the fingers.

·         The fist must be tight, loose fingers can break when hitting an object.



There is also the issue of form and thereby surface area. If someone punches with all 4 knuckles, the impact is spread out over a wider surface area then if the impact is merely over 2 knuckles. It's pure physics.

Also, if you punch without full extension (such as bent elbow or wrist), you are actually taking part of that impact back upon yourself thereby reducing the power of the punch. Similarly with poor rotation, poor "stance", or dropping your other hand, you can reduce the impact.

Most karate instructor who have studied physics, even if only in high school, are quick to point out the F=ma.

Science declares that if I want to hit the serve with more power I must find a way to generate greater velocity through utilizing Newton's mass x acceleration formula. This section explains Newton's second law of motion or Force is equal to Mass times Acceleration. It is represented by

F = M x A

Acceleration is a way of measuring a constant increase in velocity. If an object is accelerating then it is moving faster and faster.

The equation F=ma (Force = mass x acceleration) is considered the most important for your powerful punching and kicking.

Power is more dependent on natural scientific principles which involve body mass, acceleration, reaction force, balance, and proper technique than on training in any particular karate martial art.

On the other hand, great speeds may be attained by the arm or leg when propelled from the supported torso and stance, much as a stone is shot from a sling; however, this fast-moving limb does not have a large mass on impact.

To achieve both mass and speed, the arm or leg which has been shot from the torso and stance can be tensed just before impact and reconnected to the torso and thus to the large mass of the lower body which is connected to the ground by the stance leg(s). However, while this technique attaches a large mass to the limb, it eventually slows the limb down.

There is a compromise which assures that maximum momentum (mass x velocity) is available upon impact with target. Depending on the target and the strategy, various proportions of mass and velocity may be selected to contribute to produce large momentum.

This is the essence of "focus 決め(焦点) Kime."
The Japanese word kime is often translated as ‘focus.’ Among other things, kime is designed to increase the effective mass behind a punch.

In simple terms, momentum is considered to be a quantity of motion. This quantity is measurable because if an object is moving and has mass, then it has momentum. Something that has a large mass has a large momentum or something that is moving very fast has a large momentum.

Momentum is defined as the product of mass and velocity.


There is one aspect of velocity that must be understood in order to comprehend the following martial arts methods, which increase the mass behind jabs. A change in the contribution of velocity to total kinetic energy requires a force to be applied to the body over a distance. The boxer’s cross generally delivers greater injury than the jab because it possesses more KE; this is due, in part, to the greater distance it travels, which increases its velocity. More velocity means more KE, which means more potential to cause of power.

I can explain with 試割り Tameshiwari technique. Breaking (Tameshiwari) is a martial arts technique that is used in competition, demonstration and testing. Breaking is an action where a martial artist uses a striking surface to break one or more objects using the skills honed in their art form. The striking surface is usually a hand or a foot, but may also be a fingertip, toe, head, elbow, knuckle, or knee.

From a physics point of view, breaking an inch thick pine board with a hand strike may be possible even for someone who is attempting that for the first time if that person is given some proper instructions.

The key ingredient is that the person’s hand needs to move at a high speed at the point of impact with the board. In order for the hand to be moving still at a high speed when the hand hits the board, the person must imagine that the board is further down from its actual position, i.e., he should be aiming his strike at a point that is lower than the actual position of the board.

Suppose the impact has broken the board.

The larger the velocity of the hand/forearm, the larger is the force needed to stop the hand/forearm. By Newton’s Third Law, the hand/forearm will apply an equal and opposite force on the board. When the velocity is large enough, the force that the hand/forearm is exerting on the board will be large enough to break the board, i.e., the board will break before it can exert a large enough force on the hand/forearm to stop it.

The amount of KE (kinetic energy) of the hand/forearm when in motion (or the amount of energy that the hand/forearm can impart to the board) is proportional to the square of its velocity; that is why the key ingredient to breaking the board is to have the hand/forearm moving at a high velocity.

Don’t forget relaxed your body and mind, will power, self confidence, impact, ability of focusing, concentration of power, speed, tense and solid to increase mass. Therefore the purpose of tensing the muscles of the body on impact is to increase the effective mass of the technique.
