As the Earth is spinning, how much more would a kg of say, platinum, bought at the equator, weigh at the North pole?
Equator vs Pole: How Does Rotation Affect Weight?
Click For Summary
Discussion Overview
The discussion revolves around the effects of Earth's rotation on the weight of an object, specifically comparing the weight of a kilogram of platinum at the equator versus the North Pole. The scope includes conceptual considerations of weight variation due to rotational effects.
Discussion Character
- Conceptual clarification, Debate/contested
Main Points Raised
- One participant inquires about the weight difference of a kilogram of platinum at the equator compared to the North Pole.
- Another participant claims there is only a 0.3% difference in weight at either pole.
- A later post humorously suggests that the weight difference could result in receiving 3 grams of platinum for free.
- Further comments introduce light-hearted banter about selling platinum at the poles and references to polar bears wearing platinum, indicating a playful tone in the discussion.
Areas of Agreement / Disagreement
Participants express differing views on the weight difference, with one asserting a specific percentage difference while others engage in humorous commentary, leaving the scientific inquiry somewhat unresolved.
Contextual Notes
The discussion does not delve into the underlying physics or calculations that would clarify the weight difference, nor does it address the practical implications of buying platinum at the poles.
