Movement Definition

My definition of movement: when and object is moving or the person taking the photo is moving.

Google definition: Framing an image including movement.

 For example, here, there is movement that is being portrayed by light across the image. There is one stable object on the right hand corner, yet on the other side of the road, car lights portray movement down the road.

In this image you can see different steps of dancing through this technique. Even though the person is faint, it doesn't matter all that much because you can still work out what's she's doing.

On this image you can see the moment through a circular object which has been spinning- through light.

Here you can see movement by the splash of water around the wings of the bird.
