(meteorobs) terms

[Larry]

An alternative which might have a wider application is to use the term 
meteorite so as to mean a meteor or meteoroid that has come to rest( a state 
of motionless, inert, without energy, or lifeless.

But a more subtle distinction of meteor and meteoroid needs to be addressed.

A meteor at high velocity with light from ablation we agree shall be called 
a meteor.

If the velocity of the meteor is just under the velocity to create ablation 
it should be called a meteoroid, just as we would call a meteor in free fall 
a meteoroid which inherently focusses more attention on the object itself 
rather than how fast it is traveling.

In other words...."-oid" represents a reduction  in motion or velocity.

This is a reasonable definition with the needed distinctions to show..... 
Change of State.
