What is called extra attack, what is attack, what is receiving

The work that must be done in order to accomplish the purpose of the work is useful work, and it must be done regardless of the method adopted.

To do the work of moving an object with a weight of g to an upstairs with a height of h, you must do work on a heavy object w=gh, regardless of you.

Whether it is carried up along the stairs or pulled up with pulleys, without exception, it is necessary to do such a great work on heavy objects.

In order to complete this useful work, you have to do some extra work and move along the stairs.

To go up, you have to overcome the weight of the person to do the work, pull it up with the fixed pulley, you have to overcome the friction to do the work, if you use the moving pulley to pull, you have to do the work on the moving pulley and the rope, these are not what we need, but we have to.

The work done is called extra work, and the useful work plus the extra work is called the total work, and people carry heavy objects up the stairs along the stairs.

For example, the total work done by people is: w total = gh + g people h = (g + g people) h, when people go upstairs, they must provide power.

f=g+g people, therefore, it can be said that the work done by the power is the total work, which can be summarized for the sake of memory.

The following mantra is: "The purpose of work is to be useful, and it is necessary to do extra work if it is not necessary, and the work of motivation is the total work." ”

To put it simply, if you want to lift water, you must pay the force of carrying the bucket, so the work you do with the bucket is called extra work.

It's not what you need, but you have to do.

Explain a little what is called work, the concept of doing work is to move a certain distance in the direction of force, for example, if you want to move a wooden block forward, it is pushed forward by you, then you do work on it. If you just push it and it doesn't move, you don't do anything to it.

Work without contribution is called additional work.

Part of the work done by the external force is lost in overcoming the frictional force and raising the pulley itself, and this part of the work does not contribute to the desired result of our --- to raise the weight, and is called additional work.

In order to accomplish one thing, we have to do work, and when we do it, what is useful to this thing is called useful work, and the rest is called extra work.

Do the work that is useless and still have to be done.

BL (gay men) is called attacking with a male role, and the other is called receiving.

Uh, to add, I've brushed it out today.。。。 The Frenzy Pretender card in the Boar Diagram (Magic Attack +20).
