How do forces change motion?

Forces can make things speed up, slow down, or change direction. When you want an object to stop, you can push on it. When you want an object to move faster, you can use force for that, too.

Forces can make things change direction.

Forces can be strong or weak and they can go in different directions. How far you can push something depends on how much force you use. A stronger force makes bigger change.

Pulling is better than pushing

Train managers deliver feedback ( pushing is even more effective), maybe useful. But if the recipient is not ready or able to learn it, then the communicator will not have enough perseverance and skill to achieve his goal. Whatever power, whatever authority you have, it depends only on the recipient of feedback what information he will learn and what will remain outside, how much he will understand what he hears, and whether he wants to change something.

If you increase the pressure and push even harder, you rarely learn something really. It is necessary to shift the emphasis and educate not so much those who provide feedback as those who receive it. We must learn not to give it, but to receive it. Not enough to learn. You have to be able to learn.

Pull instead of push.

Pulling means learning skills that help you learn, recognize and overcome resistance in yourself, discuss different opinions with confidence and interest, learn from the discussion useful lessons - even when the feedback seems erroneous and unreasonable. This means being able to stand up for yourself, defend your point of view and ask questions. Pulling is also learning something useful by accepting feedback, even when it is unfounded, unfair, badly presented, and when, frankly, you are simply not in the right mood.

We like the word "pull" because it sheds light on a truth that is often overlooked: the key to your development and improvement is not your teacher, not your boss, but yourself. Having a good mentor is very helpful. But don't wait for it to show up in your life to start learning. Really good mentors are rare. The people around you may wish you well, but they themselves know little better than you what to do, or are too busy to give you as much time as you need, are difficult to communicate with or weak in feedback or mentoring. We have to learn from just such people, so if you are serious about self-development and self-improvement, you have no other choice but to learn well from any teacher.

To stir the ocean, one must not only push, but also pull • Alexey Gilyarov • Science news on Elements • Ecology

A giant conveyor of currents stirring the ocean could slow down significantly as a result of the melting of the glaciers of Greenland and the release of large amounts of fresh water into the North Atlantic. This is fraught with severe cooling in northwestern Europe and a reduction in the ability of the ocean to absorb carbon dioxide. However, in addition to the mechanism that “pushes” the water inward, there is a mechanism responsible for the “pull” of water upwards. Models show that the presence of such a compensating mechanism will at least partially mitigate the negative effects of global warming.

“Push” (“push”) or “Pull” (“pull”) – these inscriptions on the doors are faced by everyone who has ever visited an English-speaking country. Recently, the push or pull dilemma has also been discussed in the scientific literature in relation to the forces that set the global system of ocean currents in motion. The conveyor, which in the North Atlantic Ocean carries water from the surface to the depths, moves it at great depth over great distances, and then lifts it up again, but in completely different places, in other oceans (Fig. 1). The discovery of this conveyor, also called the "Brocker loop" after the American researcher Wallace Smith Broecker, who first described it, is certainly one of the greatest scientific achievements of the late twentieth century, which made it possible to take a fresh look at how the vertical mixing of oceanic water affects the Earth's climate. In addition to the fact that the conveyor brings heat to the north of Europe, it is also important because it carries a huge amount of carbon deep into the ocean, which in the form of carbon dioxide enters the upper layers of the ocean from the atmosphere.

The conveyor is traditionally thought to be driven by a thermohaline (i.e. determined by heat and salinity) mechanism that actually "pushes" the water deep into the North Atlantic. This water comes from the south in the form of a powerful (more than 100 Amazons!) stream moving at a depth of about 800 m. In the Norwegian Sea, where strong winds blow (Fig. 2), this stream rises to the very surface and cools significantly ( in winter - from 10° to 2°C). The heat given off at the same time determines the unusual mildness of winters in northern Europe. Cooled and, as a result, significantly “heavier” water (which was already characterized by increased salinity and, consequently, density) “sinks” - sinks down, this time almost to the bottom (see Fig. 3). A special water mass is formed - the so-called "North Atlantic deep water", which begins its long return journey through the depths of the ocean. Moving south, it crosses the equator and, having reached approximately 30-40°S, turns east. Having given a small branch to the north in the Indian Ocean, this most powerful current continues its way in a latitudinal direction up to Australia, which it goes around from the south, after which, already in the Pacific Ocean, it heads north, up to the Aleutian ridge, where its remnants rise to the surface .

Stopping this conveyor is in principle possible, and, oddly enough, it is associated with global warming and the melting of Greenland's glaciers. Then a mass of fresh water will enter the northern part of the Atlantic Ocean, which will dilute the salty waters that arrived from the south, and those, having become less heavy, will simply stop “sinking” and setting the entire conveyor in motion. In other words, the “push” mechanism will not work. This has already happened in the history of the Earth, and the last time was 11 thousand years ago, when, as a result of the melting of powerful glaciers in the north of North America, masses of melt water overflowed the large Lake Agassiz that existed there and rushed through the Great Lakes region and the St. Lawrence River to east to the Atlantic Ocean. Broker's conveyor then stopped for a thousand years, and this caused a severe cooling in Europe.

Since the water actually sinks in one place, in the north Atlantic, and rises in many places - in the Southern Ocean, in the Indian and in the Pacific, it is not surprising that the main efforts of researchers were directed to studying the forces that "push" down, and not "pulling" up. However, in a recent article by Professor Martin Visbek of the Institute for Marine Research. Leibniz at the University of Kiel (Germany), attention is paid precisely to the mechanisms responsible for the rise of water to the surface, to the forces that “pull”. As the author writes, he is still at 1994 was amazed by the results of a computer simulation of the global system of currents, carried out by Robbie Toggweiler at the Princeton University Geophysical Laboratory. The model showed that in response to increased wind mixing in the Southern Ocean and the corresponding activation of upwellings (water rises) there, the North Atlantic reacts with a more intense sinking of waters.

Obviously, to ensure the operation of the pulling mechanism, it is necessary to penetrate deeper into the warmer surface waters, breaking the sharp density gradient that isolates the upper well-mixed zone from the main deep mass. Strong storms can play an important role. They "wash out" the upper boundary of the dense lower layer of the water column, just as waves wash away the coast. Migratory animals such as large crustaceans (krill), fish, and whales may be of some importance for mixing.

Modern climate models predict that the melting of the Greenland glaciers could reduce the intensity of the sinking of waters in the North Atlantic (i.e. the “pushing” mechanism) by about 30%. But the same models predict a sharp increase in winds and more frequent storms in the Southern Ocean region. And this means that the “pulling” mechanism responsible for the rise of deep waters to the surface should be activated. The author emphasizes that it is necessary to develop a system for collecting primary data on ocean hydrology and improve models in order to get a fairly complete picture of the balance of forces "pushing" and "pulling" the ocean conveyor.
