Where Will the Candlelight Go?: Investigating Centrifugal Force

Click For Summary

Homework Help Overview

The discussion revolves around a scenario involving a horizontal plate rolling around its axis, with a jar containing a burning candle placed on it. Participants are exploring the behavior of the candlelight or flame in relation to centrifugal force.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are considering the effects of centrifugal force on the flame and questioning whether it would move away from the axis of rotation or remain stationary due to the jar's constraints. There are discussions about the behavior of a marble in a similar setup and the implications of the flame's density compared to air.

Discussion Status

The conversation is ongoing, with various interpretations being explored regarding the movement of the candlelight. Some participants have offered clarifications about the setup, while others are questioning the assumptions made about the jar and candle's mobility.

Contextual Notes

There is a suggestion that the jar is fixed to the plate and that the candle is secured within the jar, which may influence the discussion about the flame's behavior.

Homework Statement


Horizontal plate is rolling around its horizontal axis. On the plate few meters away from this axis there is a jar with a burning candle inside

Homework Equations


Where would go the candlelight/flame , i mean which side would it turn and why

The Attempt at a Solution


I think there are 2 answers for me at the moment.
Normal centrifugal force and the flame would try to escape from this rolling plate (haha i can't say this another way)
Or it wouldn't move beacose jar is new environment/center which don't lead inertial force or flame which is gas beacose of jar wouldn't have to push the air.

Hello korec123. Welcome to PF !

I think you need to do a more thorough job of describing the situation here.

Can you post an image for this?
 
I'm going to guess this is a round horizontal plate spinning on its vertical axis.
Think of a marble in the jar. Where will it go? Why?
A flame is less dense than air. Where will it go?
 
Hmm, i if there would be a marble , it will go with a jar outside the plate , going with this flame would go opposite way , i mean it would move towards vertical axis.
But what if candle and jar can't move?

I think the problem assumes the jar is stuck to the plate and the candle is stuck to the bottom of the jar.
 
so am i right?
 
Yes.
