Discussion Overview

The discussion revolves around a perceived mistake in the script of Disney's movie "Ice Princess," specifically regarding the physics of centripetal force and moment of inertia as presented in a scene. Participants explore the implications of the incorrect statement on the understanding of physics concepts among viewers, particularly children.

Discussion Character

  • Debate/contested, Conceptual clarification

Main Points Raised

  • One participant points out a specific line from the script that incorrectly states that tucking in arms increases moment of inertia, which would contradict the principle of angular momentum conservation.
  • Another participant agrees that the script is incorrect, suggesting a consensus on the error.
  • One participant expresses concern about the impact of this mistake on children's understanding of physics.
  • Another participant proposes that the wording may have been an aesthetic choice rather than a mistake, arguing that "increase" sounds more positive and questioning whether the audience would grasp the concept accurately.
  • A light-hearted comment is made about the situation, indicating a mix of humor and frustration.

Areas of Agreement / Disagreement

Participants generally agree that the script contains a mistake regarding the physics involved, but there is disagreement about whether this was an intentional aesthetic choice or a genuine error.

Contextual Notes

The discussion does not resolve the implications of the mistake on viewers' understanding or the reasoning behind the script's wording.

Disney's movie "Ice Princess" mistake?

so I watched the movie over the summer...
here's word for word out of the script

"Now, l'm going to increase
the centripetal force
by tucking in my arms.
This will increase
my moment of inertia,
so l will spin...faster."

so it's been bugging the hell out of me...if she pulled her arms in, wouldn't that decrease her moment of inertia to make her spin faster...to conserve angular momentum?

thanks.
 
Physics news on Phys.org
Yep, the script is wrong.
 
that's depressing then...Disney is going to mess up all those poor kids who actually listened to the physics in the movie
 
I think it was an aesthetic choice, not a mistake, because "increase" sounds more positive and because I could not imagine someone who had heard of moment of inertia getting the concept so exactly wrong.
 
haha that is funny
