Homework Help: Rolling candle

  1. Sep 5, 2015 #1
    1. The problem statement, all variables and given/known data
    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

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

    3. 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 cant say this another way)
    Or it wouldnt move beacose jar is new environment/center which dont lead inertial force or flame which is gas beacose of jar wouldnt 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 cant move?

    I think the problem assumes the jar is stuck to the plate and the candle is stuck to the bottom of the jar.
