Gravitational Effect of Uniform Mass on Earth's Surface

AI Thread Summary
The discussion revolves around the gravitational effect of Earth if its mass density were uniform and reduced to 2/5 of its actual value, while maintaining the same size and shape. Participants emphasize the importance of using the correct equations, debating whether to apply the gravitational force equation or the gravitational field equation. Clarity on the term "gravitational effect" is sought, with a consensus emerging that it refers to gravitational force. Ultimately, the conversation highlights the need for precise definitions and appropriate mathematical approaches in gravitational physics. Understanding these concepts is crucial for accurate analysis.

Hey guys!

What would be the gravitational effect of Earth on it's surface, if somehow the density of mass was uniform and equal to 2/5 of the real value? Assuming that the size e shape os the planet doesn't change.

Actually, do you think I should use the equation for gravitational force or the equation for gravitacional field?

I guess it depends on what you are asking - it isn't clear to me what you want to know. What is "gravitational effect"?

Analising the question again, I realized that it's Force. Ty for the help o/

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
