How much impact will a footballer be subjected to when they are hit by a football?

Own. They are all science students, but the physics formula only has few conditions, so it is not as accurate as common sense, and the 20-meter kick to you is probably fine, but if you don't notice the ball, it will be a little heavier, and if it hits the temple, it will hurt a lot, but it's okay. If you don't see the ball hitting your ribs and chest, then if there is anything unusual, such as feeling pain in the ribcage for a long time, acid reflux, and bitter mouth, then it is necessary to check.

Personal opinion, if you just want to understand the size of the force, it doesn't matter. If you want to see if it is an injury, you should ask if the title is related to medicine, and you should choose the scope of medicine.

20 meters is basically not too serious injury, unless the person's foot is outrageously strong or hits some key parts...

I used to be two meters away and it took about 10 minutes to get up.

It doesn't hurt, because it's not a matter of pressure, it's a matter of momentum, because.

mv=ft f=mv/t

Pressure p=f s=mv (ts).

The ball is soft and the contact time t is large.

You need to know what the ball speed is, and if it's a team like Carlos that is 100 kilometers away, the damage is great.

As long as you don't feel pain, you'll be fine.

How painful it hurts for foreigners to be smashed by a football? After the camera slows down 1000 times, it hurts even through the screen.

Lack of conditions, to give you how long to hit you, the speed when it touches you.

You still have such clear logic that you're okay.

There is not much impact, and when heading, you must use the forehead (pure bones are a layer of scalp) and the top of the head will definitely have a headache

As for being hit by the ball on goal, as long as it is not a vital place, it is fine, it is not as powerful as a normal man's punch It won't hurt very much anyway!

ft=mv

The amount of force you experience depends on the speed at which you give the ball and the time you make contact with the ball, to put it simply, the faster you kick the ball or the ball that kicks you, or the shorter the contact time, the more force you will be impacted.

There is no fixed value, so the player's technical action is to ensure that the contact time is as long as possible to increase the ball speed and reduce the impact force.

Can you try, head over the ball or hit the head with the ball for a headache?

That's because when you top, your head is facing forward, so the contact time is longer.

Use the forehead when heading, otherwise you will have an early brain.

Actually, it's not that scary, it depends on the distance. For example, Carlos's free kick is very powerful, and the speed is about more than 100 kilometers per hour, but it is an instantaneous speed, and then it slows down immediately, after all, the weight of the ball is not large.

In this process, if the force on which the object is required.

According to Newton's third law.

That is, the force required of the object against the football.

We can solve this problem with the impulse theorem.

fδt=mδv

In this formula, you need to know the initial velocity of the football and its speed, as well as the time it takes to act on the object, you can find the force, since this force is a variable force, so the value is the average of the force.

According to the principle that the force is reciprocal, this reaction force is equal, so it is only necessary to measure the gravity of the football first, and then measure the resistance of the football along the direction of motion, and finally through orthogonal decomposition, combined with Newton's second law to list the acceleration expression, and then combine the motion state of the object to calculate the acceleration, and substitute the acceleration expression, you can find the reaction force received by the football object, that is, the force experienced by the object.

Not only the force of the kick, but also the resistance of the air, and of course, if you want to be more serious, you have to count the force of gravity.

If it is intentional, the foul player comes forward to apologize. The referee will show a red card and send him off.

Professional football players sometimes shoot with their heads, it is the top force, and it's okay to push it out, but you are the football to give the top force, and it hits your head and bounces outward, so it should be the football that is forced. It's okay, go back and eat a few more steaks, exercise more, and exercise your body well, and it's OK to be hard.

That shouldn't be a problem, the ball is empty, it doesn't hurt to hit your head, but there will be a feeling of dizziness like you said, stay two and take a look, it should be fine.

You are more likely to be psychologically suggested. Suggestion 1: What to do and what to do, when it doesn't happen, Recommendation 2: If the symptoms persist for more than 3 days, go to the hospital for imaging tests.

Now the weather is very hot, and if you don't get hit by football, you will get dizzy and have an upset stomach.

Sleep and see if it's okay, if it's okay, it'll be fine.

If it doesn't work, go to the hospital for a check-up.

I also get kicked a lot. It should be fine.

It's best to do a check-up, just like your description, you can't confirm what you're doing.

There shouldn't be much of a problem, we play football in physical education class and smash people all day long, if it's green, you can use a hot towel to compress it, reduce the exercise, it won't be an internal injury, (it shouldn't be).

If you can't get out of bed the next day, it may be a rib fracture, and if you can get up, you will definitely be fine, and you can't die.

It should be fine, and it will be fine after a while If you are not at ease, go and ask the doctor,

There should be no problem, take a good rest, and it will be fine in a few days, and if it is not good, go to the hospital for a check-up.

Is it painful to breathe? Long time, isn't it? Generally, it will be fine, but if it hurts for a long time, it is recommended to see a doctor and take a **!

It's okay. Apply the active oil.

Possibly, it's best to see a doctor.

Generally nothing.

If you still have a lot of pain every few days, go to the hospital for a check-up.

Probably, it's better to go to the hospital for a check-up

The kicked football is in the process of flying in the air, because the foot has been separated from the football at this time, the socks will not be affected by the kicking force but are still subject to resistance or gravity, so if the air resistance is not counted, the football is only affected by gravity

Therefore, choose D
