AI Thread Summary
The discussion revolves around understanding the gravitational forces between the Sun and the Earth as depicted in a force arrow diagram. The user seeks clarification on whether the first arrow represents the gravitational force exerted by the Earth on the Sun and the second arrow the force exerted by the Sun on the Earth. It is confirmed that the user has identified the forces correctly. The clarification helps the user gain a clearer understanding of gravitational interactions. This exchange highlights the importance of accurately interpreting force diagrams in physics.

Hello,
I am trying to get my head around this, maybe someone here can help. I have a force arrow diagram for gravitational forces of both Sun and the Earth. Can someone help me name these forces please.

Am I correct in thinking that force 1 is the gravitational force that the Earth exerts on the Sun? and that Arrow 2 is the gravitational force that the Sun exerts on the Earth?
Or is it the other way around?

If I have them the incorrect way around, could someone please give me an explanation as to why they are the opposite away around
Thank you to anyone who can help me out.

You have them correct.

Thank you so much for your help, I kept spinning it round in my head.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
