Discussion Overview

The discussion revolves around the weight and mass of frying pans under different conditions, specifically comparing a frying pan in a dark room to one outside on a sunny day, and the effects of altitude on weight. Participants explore concepts related to mass, energy, and gravitational effects.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants assert that a frying pan's mass remains constant regardless of its environment, while others suggest that external factors like sunlight and altitude may influence weight measurements.
  • One participant claims that a frying pan at 500 meters above ground will weigh slightly less due to reduced gravitational pull.
  • Another participant introduces the idea that a frying pan exposed to sunlight absorbs solar energy, which could theoretically increase its mass according to the equation E=mc², although they acknowledge this increase is negligible.
  • A later reply questions the implications of gravitational time dilation on mass, suggesting that the frying pan at ground level may have more mass due to its proximity to Earth.

Areas of Agreement / Disagreement

Participants express differing views on whether the frying pans weigh the same or if external conditions affect their weight. There is no consensus on the impact of sunlight or altitude on mass and weight.

Contextual Notes

Participants reference concepts such as gravitational effects and energy-mass equivalence, but the discussion does not resolve the complexities surrounding these ideas or their implications for the frying pans in question.

Who May Find This Useful

This discussion may be of interest to those exploring concepts in physics related to mass, weight, and the effects of environmental conditions on physical objects.

What weighs more, a frying pan in a dark room, or one that is outside on a sunny day?

Which has more mass, a frying pan in a dark room, or one that is outside on a sunny day?

Which weighs more, a frying pan at ground level or one 500 meters above the ground?

Which has more mass, a frying pan at ground level, or one 500 meters above the ground?
 
Physics news on Phys.org
Maybe this should be in the physics section. Idk how to move posts though, or rename them...
 
they all weigh the same and have same mass.
 
Assuming they are the same frying pan, they will always have the same mass.

A frying pan 500m above the Earth will weight slightly less than a frying pan located ON Earth due to the increased distance and therefore slightly lower gravity.

A frying pan (the pan itself) weighs the same in both a dark and closed room; however, if you consider the effects of dust/pollen this may change depending on how dusty your room is! Also, the light from the sun will very very very gently push down on the frying pan, making weight measurements of it very slightly higher, but the frying pan itself doesn't weigh more.
 
Hmm...

So, the one outside will have absorbed solar energy. But, since mass and energy are directly related (E=mc2), the mass increases as well--although by a tiny amount.

Sunny day. E=mc2 and energy is mass, so the hotter pan would have more mass. More mass means greater mutual gravitational attraction, therefore, more weight.

This question should have preceeded the first. The hot pan has more mass, and mass weighs more. So the sunny day.

Which weighs more, a frying pan at ground level or one 500 meters above the ground?

Ground level, as it's closer to the primary mass (Earth).

Which has more mass, a frying pan at ground level, or one 500 meters above the ground?

No difference (and there's no gravitational mass dilation as there is with time. That I know of...)

On second thought... We know time slows down and mass increases with relative velocity, so if gravitational time dilation holds, would gravitational mass increase hold as well? I'm thinking this may be the difference in Schwarzschild radii we see between rotating and non-rotating BH's, as per http://en.wikipedia.org/wiki/File:Mass_Properties.PNG" .

Ok, I'll go out on a limb - the frying pan at ground level has more mass.

Hey, I'm no brainsnot, so if you have different answers and rational justifications, I'm all ears!
