You're talking about from a physics point of view, it is a MOTOR, but who talks in physics terms?

An engine(specifically a car engine- not one of your general physics engines) is a TYPE of motor... a motor encompasses MANY types of "motors"

...the same as the word ENGINE.... different scenarios different meanings... You can have your 19:1 CR d16y8 ENGINE, and a software engine, or whatever


but at the end of the day you can call an engine a motor, and vice versa like pastor troy
