Position is a way to explain where something is. Position can also mean other things:
The words which indicate position are called prepositions.
Left, middle, and rightEdit
To find which is your left hand side, hold your hands palms down, point your index fingers and stick your thumbs out at right angles. The finger and thumb of your left hand will form a capital letter L.
If the letter L you make is reversed, you found your right hand. Left and right are called opposite sides.
Middle is between up and down and is between left and right. Middle means the same as center.
In and outEdit
|In or inside (the blue box)||Out or outside (of the blue box)|
In or inside means that something is protected and surrounded by something else. Out or outside means that it is not inside something else.
Far and nearEdit
|The box is far.||The box is near.|
Far means that something is a long way away from you. Near means it is close to you. Things can also be near and far other persons and other things.
In math and physicsEdit
The position of something is where that thing is in space and time. Usually people use Cartesian coordinates to write down a position. So a scientist might say that the balloon was at x, y, z when it popped at a certain time.
