Define/explain this gravity calculation (picture)

Click For Summary

Discussion Overview

The discussion revolves around a gravity calculation depicted in an image, with participants seeking a detailed explanation of the calculation and its underlying principles. The scope includes conceptual understanding of gravity, Newton's law, and the relationship between mass, force, and acceleration.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant requests a detailed explanation of a gravity calculation, indicating it is not a homework question.
  • Another participant describes the calculation as a simple definition, suggesting the requester needs to clarify their specific needs.
  • A third participant identifies the image as a description of Newton's law of gravity.
  • It is noted that the gravitational force experienced by two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them, with a distinction made regarding acceleration depending on mass.
  • A later reply suggests that conceptualizing the objects as point sources may simplify understanding.

Areas of Agreement / Disagreement

Participants express differing views on the complexity of the calculation, with some considering it straightforward while others seek more detailed explanations. No consensus is reached on the specific aspects of the calculation that require clarification.

Contextual Notes

Participants have not specified assumptions or definitions that may affect the interpretation of the calculation. The discussion does not resolve the nuances of gravitational force and acceleration in relation to mass.

Hey guys,

Im trying to write something up, and I want a more detailed explanation of this calculation (image below) - Can anyone give it a go? Thanks in advance

I am trying to find a graphic/image that best suits calculations that have to do with acceleration and gravity, so if anyone has one, please do share! THanks

P.S. - This is not a homework question

Thanks

That is an incredibly simple 'calculation,' its basically just a definition. You're going to have to be more specific on what you're looking for.
 
The picture is simply a description of Newton's law of gravity.
 
it says that the force due to gravity each ball experiences is equal to the product of their masses over the square of the distance separating them.

note that each object experiences the same force but does not experiences the same acceleration IF they are of different masses.
 
It is easier to conceptualize if you reduce them to point sources, which is the usual practice.
