Question: Is the gravitational force in Pandora the same as in Earth? The humans are seen walking in the same way they walk on Earth.
Chosen answer: No, it's not the same, it's a little bit lighter, as mentioned by the Colonel early on in the film. That's part of why many of the creatures are so tall and lean there. Lighter gravity wouldn't really affect the way you walk - astronauts on the moon hopped around due to the bulky spacesuits.
Answer: If you divide the total length of hair by the age of Rapunzel, you get an average of about 4 feet of hair per year.
