This photo proves that representing movement is more than getting blur....
But used creatively as in Giacomo Balla's Dynamism of a Dog on a Leash is can be stunning
These images caught my eye when I Googled movement
I like the one on the right which looks like the girl is running towards us. They are part of the graphic response to the Gezi Park protests in Turkey. This link
http://www.vam.ac.uk/b/blog/posters-stories-va-collection/occupygezi-gezi-protests-turkey is from the VandA and has loads of innovative graphic responses to the conflict.
Movement is often successfully represented with swirling shapes and sweeping lines which get wider or narrower. There are some nice abstract images at this site

Many people have been here before me and not all of them were OCA students. Here
http://skyje.com/logos-depicting-movement/ there are a collection of logos designed to express movement which for businesses is synonymous with growth and innovation.
Going back to the 1920's Gerd Arntz and Otto Neurath developed a series of pictograms to represent an enormous variety of activities and situations including movement
The feeling of movement in many of these symbols is created by leaning the figures forward and using a side view so that the legs can be in a walking position. This has been developed over the years by successive countries hosting the Olympics. Surprisingly each country creates their own set of distinctive pictograms for each Olympics, to represent the various events
The top set is from Bejing in 2008, the bottom 2 are from London 2012, Olympics and Paralympics I think the 2 colour symbols work particularly well.
Movement can be suggested by drawing or photographing the definitive moment of an action
This stencil by Banksie is at the point when the flowers are about to be thrown. There is tension in the image and no doubt that it is a snapshot in a sequence of movement.
Cartoonists use lines to suggest movement such as the wagging of this dogs tail

Also there is the marvellous Tom and Jerry
For me arrows are generally directive rather than dynamic moving symbols, unless they employ other graphic conventions to suggest movement.
Some sketchbook ideas
I did a mind map and looked at different meanings for the word movement
then tried some random sketchbook ideas
Then I re-read the instructions and realised the brief was to design a symbol. I did some more research and found the work of JL Design and KORB for CCTV

For a symbol I like the dynamism of the squiggles at the bottom of the last sketchbook page which are lively and build on the letter M for movement
Generated by computer you get
of which I prefer this one as it's simpler but still dynamic. The others are too busy for my taste.
I tried some experiments to see if I could make this more dynamic
The idea was that the softer squiggle in the background would provide some tension with the bolder squiggle but I think the background squiggle is too soft therefore my preferred design is
