Xiao Ming carried the bucket to lift the bucket The pulling force object of the bucket is ??

This has to be looked at separately, because the rope is subjected to the gravity of the bucket and the hand pulls the rope, so the hand is subjected to the downward force of the rope.

But if you look at the ** of the force, it is the gravitational pull of the earth.

I remember when I learned it was a rope. Because you only look at the force relationship between your hand and the rope, the force applied to the hand is the rope.

If you are carrying a bucket directly by hand, it is the gravity of the bucket, and the object of force is the earth.

The main question is whether you see the rope and the bucket as an object.

If you look at the handle of the bucket separately from the bucket, there is a different answer.

The pulling force is a rope, which is given by the hand, and the earth's gravitational force is paid by the hand, so the direct force object is the rope, yes!! The gravitational pull of the earth, the hand is indirect1!!

Say yes choose C

The process of Xiao Ming's bucket is to overcome the gravity of the earth.

The rope and the bucket are a whole Since the bucket is subject to the gravitational pull of the earth, and the bucket is in equilibrium at this time, it must be subject to a pulling force, of course, this force is given by man.

To put it another way: that is, the pull is caused by the gravity of the bucket. These two forces are a pair of balanced forces.

That is, it is the person who exerts the pull force.

Hands, of course! Do you use rope for buckets? Even if you use a rope, it's still a hand at all! The earth is called gravity or gravity, not tension!

C should be chosen, the rope does not pull the bucket, the earth produces a downward gravity on the bucket, and Xiao Ming's hand produces an upward pull.

The gravitational force of the earth should not be understood as a pulling force, the pulling force acts on the stressed object and is in direct contact, and the rope is directly connected to the barrel, so the force object of the pulling force is the rope.

It should be a rope because only the rope is connected to the barrel. And it's for the pull of the barrel, so it should be a rope. But if a person directly carries the bucket, the object of the pulling force of the bucket is the person.

a Rope. The rope is directly connected to the bucket, and the role of the hand is the overall force object composed of the rope and the bucket.

Rope, as you know, the tension of the bucket is actually the elastic force of the elastic deformation of the rope!

c Earth, if there is no gravity, the barrel will not be forced, right?

I'm not sure

Pull, that is, the hand; Gravity is the earth.

Rope. How can there be so many garbled answers.

Rope, absolutely! Give it points!

The correct answer is: rope teasing pure Zen.

Although the force experienced by Xiao Ming is the joint action of the bucket and the water, Xiao Shan Chenming's hand directly acts on the rope, so the force object of the pulling force on Xiao Ming's hand is the rope.

Analysis of the shoot is wide:

According to the definition of the schematic diagram of force attack, the direction and application point of the tensile force on object A can be expressed

The tensile force of the bucket acts on the connection point and direction of the rope and the barrel vertically upward, as shown in the figure Comments: Clarifying the direction and action point of the force is the key to correctly representing the schematic diagram of the force

The bucket placed on the ground is subjected to the force of gravity and the supporting force of the ground on it, and the two forces are equal in magnitude and opposite in direction, which is a pair of balanced forces, and the bucket remains at rest

So the answer is: heavy; Yes

Answer C analysis: Force is the interaction between objects in a hurry, the object that exerts force on the object is the object that exerts force, and the object that receives the force is the object that receives the force

Answer: The bucket is connected to the rope friend Chang Haozi, and the bucket moves upwards under the pull of the rope, and the rope is the force object

Therefore, choose C Comment: This question examines the judgment of the object of force exertion, and it is a basic question

Answer C Analysis: Force is the effect of the state banquet judgment book on the object To produce this force, there must be a force object and a force object The force object is the object that exerts the force and the force object is the object that is affected by the force So the answer should be C

d Force is the interaction between objects. Hand pull rope: The hand has a pull on the rope, and at the same time the rope has a pull on the hand. The rope pulls the bucket: the rope pair learns that the bucket has a pull force, and the bucket has a pull force on the rope.

Therefore, the rolling hand is subjected to a vertical downward pull, and its force is mainly applied by the object of the rope.

Answer C test question analysis: Force is the interaction of objects to objects, and the answer can be obtained by analyzing the force of the force applied by the object and the stressed object The force is the interaction between the object and the burning body, and the pulling force is the interaction between the rope and the hand The stressed object is the hand, and the force object is the rope Therefore, choose C Test point: The concept of force.

Point Trace False Evaluation: This question mainly examines the interaction between objects, and finds the force application object and the force object
