definition of rotation

Action of turning around an axis

The term Rotation refers to the action and result of rotating, that is, turning around an axis. Rotation is basically a movement of change of orientation, so that given any point of the same it will remain at a constant distance from the axis of rotation..

Typical movement of the planet earth and that marks the beginning of day and night

Furthermore, Rotation turns out to be one of the movements made by the EarthBecause the aforementioned planet, being an ellipsoid body flattened by the poles, performs four main movements: translation, nutation, precession and the aforementioned rotation.

Regarding the rotation of the earth is the movement that makes rotate on itself along the earth's axis, imaginary this one of course, that passes through the poles.

A complete revolution of the earth if the sun is taken as a reference takes 24 hours. The solar day therefore has 24 hours, while, if the stars are taken as a parameter, the complete turn lasts 23 hours, 56 minutes and 4 seconds. The difference appears from the advancement of the earth in its orbit.

The rotation of the earth with its proximity to the sun is what determines the day and night. That region of planet earth that is facing the sun will be the one that will have day, while the other part, that is, in the rest of the world it will be at night, not receiving sunlight until the rotation is completed.

The ecliptic is that curved line along which the sun appears to rotate in its apparent movement from the earth.. The obliquity of this line is the angle of 23.5 that the earth's axis makes with respect to the normal of the line. This inclination is what causes at the poles there are long months of light and dark depending on the incidence of solar rays.

Alternation of something

Another meaning of the word is that which refers alternation or variation of any issue. "A rotation in the positions began that will last until the end of the month according to the directives of the new manager."

Staff turnover

So it is possible, as we demonstrate with the previous example, that we talk about job rotation, personnel, that for different needs of the companies change area or sector or also rotation can occur in terms of shifts and work schedules .

Those companies that offer 24-hour customer service to attend to the claims of any type of their clients, for example those that provide internet, have a staff that answers those calls and that is organized in different shifts and days in order to respond effectively to demand. Meanwhile, it may happen that due to a specific situation, the shift rotation of an employee is decided.

Now, we must say that staff turnover is not always looked upon favorably and produces positive results in the company that is practiced. In principle, a company that causes constant staff turnover, either due to layoffs or because they resign, usually generates mistrust towards the company. This situation also threatens the bond that the employee has with the company and that is important for him to do his best for success.

It is only seen with good eyes when the turnover is the result of hiring more trained personnel and the consequence of an injection of investment.

Crop rotation

Crop rotation It is the variety of alternative plantings, or in their absence simultaneously, that are implemented to avoid that the land is exhausted in the exclusive feeding of a single plant species and also with the mission of avoiding pests and ensuring better care of the soil.

Among the various variants that are proposed for crop rotation, we can highlight that of supplanting the sowing of cereals by that of legumes. In other words, the idea is that the alternating crops do not belong to the same botanical family as the previous one.

Experts advise that if, for example, vegetables that demand a lot of nutritional requirements are planted, once the harvest ends and is harvested, the ideal is to replace the proposal to give air to the land in question and for example plant legumes that will enrich the land to the fix nitrogen.
