This word is derived from the Latin "rotatio". Rotation is the action that a body can exert to roll or turn on its own axis, which can be a line or a point that remains fixed, it is called the axis of rotation.
Rotation is basically the movement of a body where its orientation changes, in the same way the body has the ability that while it is rotating, any point that belongs to it will maintain the same distance with respect to the axis of rotation (despite its movement) At the end of the turn or turn, the body returns to its original position, indicating that a complete rotation has been made, which can be done several times, that is, the same body can rotate around its axis at different times.
There is the oscillatory rotation that occurs in the movement that is present in a pendulum, which occurs when the energy used to make the turn is high and it can complete it. Also in astronomy this term is used to refer to the turn that the earth makes on its own terrestrial axis which is imaginary and crosses the poles, this turn when completed (taking the sun as a reference) takes 24 hours, and from this movement arises day and night thanks to the closeness that the earth has with the star king.
In the field of mechanical engineering, revolution is known as the complete rotation of a body or system on an external axis (another body), for example the movement that the translational earth makes with respect to the sun is a movement of revolution, here We can see that the external axis of the earth is the sun, and it revolves around it, this movement of revolution takes a year to complete.
On the other hand, it can refer to the variation or alteration that may exist in different issues, in the workplace this term is widely used, for example, when referring to a rotating work shift, it refers to the fact that there is no fixed shift or schedule, but it may vary depending on the day of the week or the shift of the other colleagues, etc. In the world of sports there is a rotation of players on the field of play. In agriculture, there is crop rotation, which is the variety of crops in a field so as not to exhaust its wealth. Among others.
