Should a person walk and turn his body to tilt in the opposite direction of centrifugal force?

Your understanding is correct. When the speed is slow, the body does not tilt and can provide enough centripetal force by friction alone, but when the speed is large, the required centripetal force will become larger, and friction alone is not enough. So the body will tilt to replenish.

No matter how fast your body weighs less, you may have to find a support, just like on a bus, when you turn fast, you have to hold the handrail of the bus, which cannot be adjusted by your body alone.

First of all, there is no error in the title.

The direction of centripetal force is the opposite direction of centrifugal force.

Some netizens said no, no need to tilt, just say that the friction is fine, I personally feel that it is not quite right.

This doesn't make sense.

This brings the issue of torque to life.

When the human body is walking or running.

It is not only about balancing the forces.

And it has to have a net moment of zero!!

I don't know what school you're in.

Mastery of torques is not required at the middle and high school levels.

That's why you have a question!

None of the people upstairs thought about the torque.

So the explanation is not comprehensive.

The title is correct, people should be inclined in the direction of the centripetal force (the direction of the inward bend of the bend), that is, in the opposite direction of the centrifugal force, in order to provide the centripetal force.

Keep the object from falling, as long as the center of gravity (the resultant force of gravity and external forces (e.g., centripetal force after tilting, wind force, etc.), but excluding the friction of the ground) does not exceed the support surface. It's not that when it's slow, you don't have to fall without leaning, but you feel "a little bit uncomfortable".

It is wrong to say that friction is fine.

The friction force is on the ground, there is no height, and people have a certain height of the center of gravity, in order for people to have a stable center of gravity when running, the human body must have an inclination.

If you're walking, you don't need to, the air resistance and friction are more than your centripetal force.

But if you run, it's different, it's very fast, plus your own inertia, if you don't have a centripetal force and a tilt, then you're flying out, and you want to see it often in short track speed skating, and the inclination is very obvious when cornering, in short, as long as you have to overcome inertia and do work when cornering, then there must be a centripetal force.

The resultant force of friction and gravity, etc., is shown as a centripetal force. The greater the speed, the greater the centripetal force.

When turning quickly, you should tilt your body and use the component force to resist the centrifugal force of Huipei.

Walking is actually inclined to tilt, but due to the slow speed and small centrifugal fiber, the angle of inclination is also very small and not easy to detect.

Also, biomechanically. Before walking upright, Gao Wei himself was shaking from side to side, relying on left and right shaking to constantly adjust the center of gravity.

The tilt is to balance the centrifugal force when turning.

The faster the speed, the greater the centrifugal force, and the person you need to lean your body when running.

If you can walk fast enough, your body will also need to be tilted.

It has to do with velocity, which is circular motion in physics.

No need to ......

The speed at which a person walks is very small, the centripetal force required to turn is also small, and the friction is completely fine.

But the most important thing is personal habits, you can lean a little if you want, as long as you don't fall.

Probably not, but everyone has their own habits

Does it matter? You're not going to fall.

If the body only twists when walking, the whole body will not lean in the direction of centripetal force; If it's like a racing curve, it must lean in the direction of centripetal force, but it's rare to see people walking in this way.

Look at the way, if you say arc, then it's a matter of the size of the centripetal force! If it's a simple turn and it's slow, for example, a soldier's right turn, then the turn requires friction!

Yes, it's so slow that the tilt is barely visible.

Affirm that the former is justified, and the latter is wrong;

Taking the earth as a reference, if only the body is twisted, it will not tilt in the direction of the centripetal force for the whole body, which is actually the rotation of its own central axis, and the centripetal movement in the body; If it is a curve, it must be inclined in the direction of the centripetal force, but it is only a matter of the magnitude of the centripetal force, but because the walking speed of the person is too slow, this inclination angle is very small. When people run fast, faster, this angle is obvious.

Hello! Friction is perfectly fine. Not exactly.

The friction force is on the ground, there is no height, the human body must have an inclination, the centripetal force required for turning is also small, and the person has a certain height of the center of gravity, if you want the center of gravity to be stable when you run, the speed of walking is very small.

When in doubt, please ask.

Which netizen said that he took it out and beat it up first.

When turning, it can be regarded as a small circular motion, and there must be a centripetal force to do a circular motion, and the horizontal component of the body that is always inclined towards the curve is that force. So the body must always be leaning towards the curve to provide centripetal force.

1) The tilt of the human body is to obtain the centripetal force of the turn, the centripetal force of the turn is provided by the static friction of the ground f, and the tilt of the body is to obtain f; The force analysis is shown in the illustration: the gravitational force mg is balanced with the supporting force n, and the centripetal force can only be obtained by frictional force.

2) You lean in the opposite direction, but accelerate the process of dumping The main reason is in yourself, in fact, the principle of your rescue is the same as the turn, the reason is that your timing is not right, or you are not skilled enough to ride a bicycle, remember, when riding, which direction you deviate, f will point in which direction, if you want to save the inclined bicycle, it is better to practice more, hehe!

The force analysis will be given to you tomorrow, but it can't be passed on today!

Instinctively leaning the body in the opposite direction of the bicycle will cause the actual centripetal force to be less than the required centripetal force and cause the bike to tip over (i.e., not complete the turn).

Keep the center of gravity still on the bike, you go to one side, and that center of gravity goes out and falls down shortly after.

The plane will tilt when it turns, and it is based on the earth; Whether the passenger's body is inclined or not depends on the reference object you choose, choose the earth as the reference, the passenger's body is tilted, choose the aircraft as the reference, and the passenger's body is not tilted.

The plane will tilt when it turns, and the passenger's body will tilt, but it will not be noticeable.

The problem of inertia, there must be. It's just the other way around.
