What Constant Results from Manipulating Gravitational Force Calculations?

AI Thread Summary
The discussion centers on the calculation of gravitational force between two massive bodies using the formula F = G(m1*m2)/r^2. Participants question the assertion that manipulating this formula would yield a constant result of 9.8N. Clarification is sought regarding the gravitational constant G and the proper application of units in the formula. The consensus is that gravity cannot be simplified to a single number without considering the specific masses and distance involved. Accurate calculations require adherence to the established gravitational force formula rather than arbitrary manipulations.

If the gravitational force between two massive bodies were measured and divided by the product of their masses, and then multiplied by the square of the distance between their centers of mass, what number would result?

is it 9.8N?

How did you get that number, show your work!
 
No it isn't. What's the formula for gravitational force? And especially put in the units. You will easily see you aren't left with just N.
 
G= 6.67 X 10-11 N/kg2/m2
 
That's Newtons graviational constant. What is the whole formula for gravitational force? hint: it contains the constant you mentioned.

Gravity ISN'T calculated that way. And if it were, or if you used the correct formula, do you really think you would always get a single number, regardless of what those masses and distance are? Please go back and read the question again. What you have written is nonsense.
 
Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
