The lever of the badminton, the badminton racket is a labor saving lever or a labor intensive lever?

The first thing to be sure of is that badminton does have a lever principle in it.

For example, when you hit the ball, you are holding the racket with your right hand, then the back of your hand is a central fulcrum, and the other end is the force point. This is the principle of leverage in badminton.

But it's not about hitting the ball.

If you study high school physics, you know that everything is elastic, especially planes and lines, they are highly elastic, and objects deform under the action of force, and there will be a tendency to regain their shape.

The string of the badminton racket is basically made of nylon material, so the deformation is large, that is, the elastic potential energy accumulated during the deformation is large. Then, when we hit the ball, when the badminton head touches the surface composed of our badminton racket string, the badminton surface accumulates a certain amount of elastic potential energy, plus we swing the racket to give the force to the badminton surface, so that the overall mechanical energy accumulated on the badminton racket surface increases to the maximum, at this time, the tension of the line reaches the maximum, and the elastic potential energy also reaches the maximum, and it begins to recover its shape between five and six thousandths of a second, which puts all the mechanical energy (elastic force energy +The kinetic energy of the force of the racket is converted into the shuttlecock at once, and it is converted into the kinetic energy of the shuttlecock in the opposite direction. We know from the mass (kg) * (the square of the velocity) that we can reach a very high speed with only 500 N of force.

So, with regard to elasticity, in a finite number of surfaces and lines, if a constant force acts on the midpoint of the surface or line, the maximum force is converted into the elastic potential energy of the surface or line. Therefore, the place to really hit the badminton should be a little above the middle of the badminton racket (because our swing is a circular movement, so the larger the radius, the greater the force, according to a certain speed). So all things considered, the sweet spot is the area that makes your most effortless shot is the middle and upper part of the racket.

Hello classmates, I'm only in my first year of high school now, but I'm very interested in physics, and I like to play badminton, or let's be friends? 259164848

A badminton racket is actually a lever of force, and since it is a lever, it must have a force branch.

The support point, the finger is the support point of the force of this lever. This point is not big, but it can play an explosive role, just like a small ant can hold up an object that is several times or even dozens of times heavier than its own body.

A small wooden stick needs to pry up thousands of pounds of objects, and it needs to have a fulcrum (a brick, a small piece of wood, a small piece of iron, etc.) as a support point for the force. In fact, killing, splitting, hanging, pushing, hooking, rubbing, blocking, etc. in badminton are all completed by the twisting of the fingers.

Yes, the backcourt ball should hit the center of the racket (sweet spot), but instead of adding the correct flexion of the fingers, you should control the angle of the racket, about 45 degrees is the best, and add the force of the wrist, the greater the strength (if you are an amateur, the strength depends on your own strength).

Yes, the backcourt ball should be hit in the center of the paddle (sweet spot) and the right flexion of the fingers.

To be clear, the "sweet spot" is the best place to hit the ball at any given time.

As for the principle of leverage, as it was said upstairs. However, everything must be based on facts, and find a grip that suits you in continuous practice.

It should be the center of the racket, not the tip.

Through the combined action of turning, arm throwing, wrist shaking and finger flexion, the ball can fly to the opponent's backcourt.

Maker: konoyoko has nothing to do with the grip point, I can pull to the backcourt with a high grip, and the most important thing is to coordinate the twist and whipping action Also, the sweet spot position of each racket is different, but the center area of the racket is generally the sweet spot.

Let me put this question on the position of the badminton racket.

1.The sweet spot is not located in the center of the noodle, but in the upper center. It's not even the top. The way to judge this is to use your fingers to flick the net, and the crispest part of the echo is the sweet spot.

2.Hit the backcourt with the racket as far back as possible so that you can hit the ball to the backcourt more easily.

3.When killing the ball, you should try to hold the racket as far forward as possible, because the ball in the front court needs more angles.

4.Nowadays, many of YY's rackets have square heads, in order to expand the sweet area to achieve the purpose of perfect attack.

Laborious lever, his power arm is shorter than the resistance arm, so laborious, is laborious lever.

It depends on where you hold the racket. The more you move forward, the more laborious it is, but the racket is short, and the ball before hitting the net is flexible and reacts quickly. The smash ball can be held far back and has a lot of power.

Laborious levers, long arms are much longer than short arms.

Badminton rackets are laborious levers.

It takes a lot of leverage, and it's also a lot of work to grab it back.

Inertia, free fall, there are a lot of them in this physics book, the phenomenon of light principle is useless, go and see for yourself.

I can only play ball, and the school's stuff has been handed over to the school.

If it's a question of playing badminton, you can talk about it.

Control and force of the wrist.

Finger flexion should mean pressing down on the wrist and fingers while killing the ball, so as to increase the force of the kill.

Generally, when you are not hitting the ball or do not need to hit the ball hard, you only need the thumb and index finger to control the racket, and the rest of the fingers can be relaxed. At the moment of hitting the ball hard, the rest of the fingers need to work with the thumb and index finger to suddenly exert force.

Use your thumb and index finger to control and support the racket, with the rest of your fingers relaxed, and use your thumb and index finger as fulcrum at the moment of impact, and the rest of your fingers quickly grip the racket for power.

Finger flexion refers to the following: Before hitting the ball, the thumb, index finger and middle finger are relaxed, leaving space between the palm and the handle of the racket. To meet the relaxation requirements, the thumb and index finger should be attached to the handle of the paddle and should not be clenched too hard.

When hitting the ball, hold the racket handle with the index finger and thumb, hold the racket tightly with the middle finger, ring finger and little finger, use the thenar muscle at the end of the thumb and palm as the fulcrum, and the remaining fingers as the force point. Bend your fingers to hit the ball, you can get the maximum power, use your fingers well, the whole force action will become smaller, the ball speed will be faster, and it will be easier.

I'll take the right-handed grip as an example, if you're left-handed, it's the opposite, and here's how to do it:

1. Before you are ready to kill, turn sideways, put your left foot in front, land on the toes of both feet, and step back with a quick backward step so that the point of hitting the ball is above your right shoulder. Because if you hit the ball far behind, you can only play high.

2. Lean back before killing the ball, basically into a bow shape, so that you can use all the strength of your body.

3. Before killing the racket, the grip must be relaxed, and there must be a gap between the palm and the racket handle, which is the most important, because only by relaxing first can you use the strength to kill the ball, otherwise if the grip is always tight, the strength of the wrist will definitely not be able to be used. Hold the racket tightly at the moment of hitting the ball and try to hit the ball.

4. Before killing the ball, the arm should first return to the ring to guide the racket, and the moment of killing the ball depends on the explosive power of the wrist and fingers (the fingers are mainly the index finger), just like whipping, which is also the focus of all backcourt techniques in badminton, and tennis, never rely on throwing the big arm to exert force, otherwise the ball will not have speed and will hurt you after the pass.

5. The moment of killing the ball depends on the explosive power of the wrist and fingers (the fingers are mainly the index finger), just like whipping, which is also what all the backcourt techniques of badminton pay attention to, unlike tennis, never rely on throwing the big arm to exert force, otherwise the ball will not have speed and will hurt you after passing.

6. If you want to hit the jump kill ball, then when you take off, it is probably when the ball starts to fall, and the legs should be slightly bent first, and the jump kill ball should be jumped and killed by the power of the toe kick, and then turn around immediately after the kill, the left foot is behind and the ground first, and the right foot will return to the center of the field after landing.

The big arm drives the lower arm, and finally the force is sent through the wrist, not just by wrist force. If you only use wrist strength, your wrist will not be able to stand it and will be easily injured.

The professional way to play is to use the wrist hard.

The unprofessional penalty is arm force.

1. This is the usual forehand grip to hit the ball. When hitting the ball with the forearm spin, turn the fulcrum at the lower end of the racket handle. A more typical example is Xiao Jie's demonstration. She mentioned that the forearm has the most internal and external rotation.

2. This is also the usual forehand grip to hit the ball. The difference is to press down on the wrist. At this point, the pivot point of rotation is at the wrist. The most typical is the demonstration of Xiong Guobao. The two methods are much the same. It's just that the way to swing the ball is different.

3. This is the usual backhand shot. If you hit the ball with the outer rotation of the forearm, the pivot point is at the lower end of the racket handle like the forehand. If you turn back by the wrist, the fulcrum will also move to the wrist.

4. Most people will feel that the backhand handling of the ball is more delicate than the forehand in many cases. I think it's possible to unconsciously turn the fulcrum in advance, close to the position of the index finger. This shortens the distance between the torque fulcrum and the balance point), and the little finger can be buckled inward to assist the force.

Because there are two points of force, it is easier to master the power of the shot. I've heard of finger twisting, maybe that's the case.

The power is mainly generated by the strength of the wrist, shoulder, and waist, and the most important thing is to grip the racket, and it is difficult to exert force if the grip is not correct.

Try to hit the ball in front of you, in front of your head, and hit the ball as high as possible, with your arms straight, so that it will be comfortable and effortless. When directing the racket, relax your fingers and wrists, and tighten the ball again when you hit the ball. Keep an eye on the incoming ball, prepare the racket in advance, and lower the racket behind your shoulder before swinging the racket.

Almost, practice the movements in place first, and then take your time.

1. You can take the badminton however you want, in fact, there is not much introduction to how to hold the badminton.

2. Keep your grip as relaxed as possible so that you can maximize the strength of your wrist.

3. Strive to hit the ball in front of the body, and never let the ball fall below the height of the neck, otherwise the ball will not have attack power.

5. Be sure to control the strength when serving, some pot friends can not effectively control the ability in the case of playing table tennis, it is very easy to knock the ball unconscious, and so on after being able to manipulate the ball, please train yourself from the four corners to the four corners of the football field opposite, because the four corners can make the enemy run far away.

Play the long ball from the back corner to the opposite side and then release the ball to the front corner. From the rear two corners to pick the opposite side of the two corners, put the side of the rear two corners of the ball, a total of 446 style of play.

Start with your left leg in front of you, touch the ground with both feet, and step backwards with a quick step back so that the tee point is in front of your left arm. Since the tee point is behind, the only way to play is to play high.

1. Understand that this "whipping" action is actually a process of acceleration, a process from stationary - slow speed - acceleration - maximum speed - relaxation. This process is at the heart of almost all badminton techniques.

2. Lifting the whip - lifting the racket in badminton technique;

The whip is raised upwards – the badminton racket swings back;

The whip is whipped from top to bottom – the badminton racket is flung from back to front;

The tip of the whip hits the top - the badminton racket hits the shuttlecock;

The final action is the same, and that is to relax.

The correct grip is conducive to the formation of a "whipping" motion.

It is important to note that the subtle differences in grip can also affect the power and swing speed.

3. Mistake 1: The tiger mouth does not grasp the handle of the racket at the moment of hitting the forehand.

The index finger and thumb are lightly clamped to the left and right sides of the racket before swinging. At the moment of swinging the racket, there is a backward force because the racket encounters resistance, and the correct grip should be the tiger's mouth close to the racket handle, and when the ball is hit, it will return to its original position.

If this is not the case, just use the middle joint of the index finger and thumb to tightly grip the racket, which will inevitably cause the grip to be not tight enough, so that the swing speed will decrease, thus affecting the final force action.

4. Mistake 2: The thumb and index finger are flush when holding the racket with the backhand to hit the ball.

The index finger is slightly higher than the thumb when holding the forehand, which is known as the correct grip. The principle is to hit the ball with the palm facing outward, the index finger behind and the thumb in front. When the two fingers are used at the same time, there is a difference in height, and there will be a lever from back to front, so as to improve the efficiency of hitting the ball.

It's the same with a backhand. The correct backhand grip is when the thumb is raised above the index finger, which is close to the other fingers. When exerting force, the four fingers exert force inward, and the thumb finger exerts force outward, because there is a height difference, which improves the efficiency of work.

This is because the hand rubs against the racket when the force is exerted, and the cocoon is sharpened when the friction is repeated repeatedly. When serving, the shuttlecock should not be placed more than the belly squeeze.

When serving, the shuttlecock should not be placed more than the belly table.

Badminton is divided into forehand grip and backhand grip, the handle of the badminton racket is faceted and edged, and the forehand grip is used to hold the racket when serving, and the thumb is held on the largest surface of the handle, which is the service grip. When serving, it is the forearm that drives the racket to make the serve smart!
