That is one way to define a position, although it is not the only way. My position, for example, is defined by an address, which tells where I am in relation to a particular street in a particular city. The street and city are not moving with respect to myself (one could argue that they are moving with respect to the sun, but that is irrelevant to the problem of determining my own position). So the speed of that street would be measured as zero. The address, nonetheless, specifies my location on the street, even though at every address on that street, the speed of the street remains zero.

A binary relation is a relation, such as "is less than" or "is the daughter of", which makes statements about pairs of objects, being true or false depending on the objects.
Manipulative movement skills can be defined as having control over the movement of your hands in relation to other objects. They are also body movements such as pushing or kicking.
