What does it mean to rotate?

Answer 1

Rotation in astronomy means how long it takes for an object to rotate once on it's axis. [See related link]

Imagine a ball with a spike through it. If you spin the ball once, so the same spot is facing you, this is rotation. It's what a day is called on a planet. One rotation around it's axis.

Revolution on the other hand, is the time it takes a planet to orbit the Sun or a star and this is what a year is.

Answer 2

the world rotate means to go around something whether big, small, tall, short, sphere etc. To spin around an axis In the retail business, it means to place the new merchandise behind the older merchandise to keep the stock "fresh". An object that is rotating is spinning on its own axis. Think of a skater doing an axel. She/he is spinning around an axis that goes through the body from head to foot. An object that is revolving is in orbit around some other body. The earth rotates on its axis causing the daily cycle. The earth revolves around the sun causing the yearly cycle.

Answer 3

It means that an object something turns around - moves around an axis within the object itself. For example, the Earth turning around once a day (more precisely, once every 23h 56m), to produce the day-night cycle.

Answer 4

Rotating the stock is also called "first in first out" or "FIFO." It means to sell the old product before selling the new. There are three basic ways to do it, and the method used depends on your stocking system. The first method is used when you just have a shelf. You've been to the supermarket and seen how the canned fruit is sold--you can't get behind the shelf. If you want to rotate stock on the shelf, you must remove all the old stock, put the new at the back of the display, then put the old stuff in front of it. This isn't done very much for the obvious reason: it costs money to have someone do this. The second is done when you're selling things like milk or soda from a reach-in cooler that has space to walk behind the product racks. Customers take what they want from the front of the shelf; employees enter the cooler and put new product on the shelf behind the old. The only real disadvantage of this system is the cooler itself--it's huge. You can also do this with one of those gravity-fed racks for things like caulk--employees put the new tubes of caulk in the rack at the top, and customers take them out from the bottom. The last one is when you sell something so big one of them takes up the whole shelf. We did this at Home Depot--we dated each item when it arrived. When someone bought the one on the shelf, we pulled the oldest one out of the overhead and put it on display. This only works when the product takes over the shelf, but when it can work it works very well.
