The discussion revolves around the question of whether gravity depends on atmosphere, exploring various factors that influence gravity and gravitational force. Participants engage in a mix of conceptual clarification and technical reasoning related to gravity, mass, and atmospheric effects.
Participants do not reach a consensus on the relationship between gravity and atmosphere. Multiple competing views are presented, with some asserting gravity depends only on mass, while others introduce additional factors such as distance and density.
Participants express varying definitions of gravity and gravitational force, leading to confusion and differing interpretations of the original question. The discussion includes assumptions about the nature of gravity and its relationship to atmospheric conditions.
You mean something like these?JLowe said:He commented on the strength of Earth's gravity varying at different places. This is not really a density issue but a distance from the center issue. Otherwise, the strength of gravity would be weaker if you were in a boat then on land at sea level.
