The discussion centers on the interpretation of gravitational forces as described by Newton's Third Law of Motion. Participants clarify that gravity pulls objects towards the Earth, while those objects exert an equal and opposite force upward against the Earth. This interaction illustrates the concept that both the Earth and the object experience gravitational attraction, leading to a mutual force exchange. The conversation emphasizes the importance of understanding these forces in the context of mass and acceleration.

This is Netwons's Third Law, two object exert force on each other in equal magnitudes but in opposite directions.deuce123 said:Homework Statement
My professor said that since gravity pushes down any object on earth, the objects themselves push up against earth. Intuitively this is difficult too grasp, can anyone give an example or anything to help me out. Thank you

That might be a bit confusing. I guess you mean "down" from the point of view of the object's gravitational field, i.e. up towards the object in terms of normal up and down.Austin Hook said:the gravity of the object is also pulling the Earth down.
