Brem,
lower notes have more "resistance" from the horn as they are more resonant. This is a function of basic horn theory. It takes more work to get the vibration set up, but once it is set up, the horn does more of the work. When you lip up, you are going to a note with less resistance that means less work (but also less amplification). The differences are not so great that you can conciously "measure" them but your lips respond appropriately.
There may be some that say their horns get harder to play up high. That usually has more to do with their body use, tongue and embouchure than the physics aspect of the horn/mouthpiece. When we stop "leaning" on the upper register, it generally gets much, much easier.
These explanations are very simplified. There is an awful lot going on when playing a trumpet!
