Does a person carrying a bucket and not moving consume a person s work?

When people carry the bucket and do not move, they need to exert an upward force to overcome the gravity of the bucket, and they do not do work, but when people have been exerting force externally, the human body will consume energy, and these energies will come from food in addition to their own existence, and people can stand or exert force outwards to exert energy themselves, and there will be heat loss when sweating, in order to maintain the normal work of the human body, the chemical energy stored in the body will be converted into internal energy to supplement the loss of heat. Therefore, although you don't do any work when you carry the bucket, you will be tired.

First of all, it is clear that there are two prerequisites for doing work:

1.Forcefully acting on objects.

2.The object produces displacement in the direction of the force.

The man carried the bucket and did not move.

Therefore, man did not work on the barrel!

Theoretically, it does not consume energy. It is important to note this "theoretically".

It's like if you add an extra weight to an object that is still on flat ground, it will also not consume energy.

But people need energy to maintain this posture when standing, because the bones and joints are not flat, we need to tighten the tendons to stand, not to mention the need to mention an extra bucket, which undoubtedly increases the energy required by the human body to maintain a standing posture.

Hope you can be satisfied with this answer.

Where does the strength come from? It is the heat generated by the metabolism in the body, and when people lift the bucket and do not move, they must keep it in a state of lifting, and how to lift it if they have no strength, that is to say, the chemical energy in our body is converted into heat energy.

No work is produced because there is no distance in the direction of force.

The human body is not a rigid body, and the immobility of the bucket requires the muscles on the opposite side of our body to be in tension (deformation) from the bucket...

When a person carries a bucket, the muscles are not in a natural state, so maintaining this state requires energy consumption, so they will feel tired.

Don't you feel your hands shaking when you carry the bucket?

When the jitter is upward, you work on the barrel;

When shaking down, convert the work you just did into internal energy.

It's a joke. The landlord is right, there is indeed only internal energy, it may not be a lot, but people must be tired when they feel tired.

It is the chemical energy that is converted, and what is produced is the internal energy.

The amount of internal energy is related to the way it is lifted and the muscle structure.

The meaning of work done is that the object moves some distance in the direction of the force. Be in the same direction as the force.

I suspect that there is something going on inside the human body, but I can't test it and it's hard to observe.

I really didn't do any work, but my arm was pulled all the time, the force was still there, and my shoulder was very sore.

When carrying a bucket, people need to overcome gravity, and when carrying a bucket, there is no distance, so we say that people have not done work,。。 Feeling tired is to use a pull equal to the weight of the barrel but not to work... There is no energy transformation ... Not converted into heat ...

I'm going to ask the creature about that

Although people carry water, they do not do work, but the earth has a gravitational force, and this gravitational force does work downward. We lift water upwards, so there will be energy consumption in this link.

Because a bucket of water is held in the hand, there will be potential energy, and the gravitational pull of the earth will have to be overcome, so the human body will have energy consumption.

People carry buckets, although the bucket does not do work, but the bucket itself is affected by gravity, and people want to keep the bucket from falling to the ground, they have to exert force and consume energy.

Because it takes effort, the barrel is attracted by the gravitational pull of the earth, and if you want to lift it up, you have to create a force of resistance.

Although it seems that carrying a bucket of water in place does not do work, the energy consumption of the human body and muscle contraction are very related, and there must be a powerful effect between people and water, which will definitely consume a certain amount of body energy.

This is because although people do not do work in physics, they still generate a certain amount of load for the human body, so there is energy consumption.

This is because although there is no work, the human body is in a state of stress, so there will be energy consumption. This is because the energy is consumed to counteract the interaction forces.

Although on the surface, there is no displacement of people, but in fact, the various fibers in the human muscles are constantly moving, and it is their movement that leads to the consumption of human energy.

Although people do not do work on the bucket, the muscles of the human body will contract when carrying the bucket, which will also consume the energy of the human body, and there is also the effect of the earth's gravitational pull.
