When something develops, there are usually certain changes to that effect.
To determine how allele frequency changes - APEX
We say that it moves.
When it changes position or something to do with the speed.

A person walking is an example of a change in position over time.

The semicircular canals and the sacs are filled with fluid and lined with hair cells. As the head changes position, the fluid in the canals also changes position. This causes the hair on the hair cells to bend. This action, in turn, sends impulses to the brain that enable it to determine body motion and position.
"Rate of change" means how quickly something changes. Examples in physics include a speed as a rate of change of position - if your position changes 10 meters every second, then that (10 meters/second) is your rate of change of position, or your velocity. Or if your income increases by a thousand dollars a year, then that's the rate of change of your income - how quickly your income changes.
You can tell if something is moving if it changes positions. A car that is being driven down the road would be moving since it is not staying in one position.
Something that is in motion changes position, the position of the object is described relative to another object. If you chose the tree as a reference point, then the object in the pictures has been in motion because it has changed postions relative to the tree.
