A little typo there. And G is gravitational constant.CWatters said:The force between two bodies is.. GmM/r2
F = (GmM)/r2
F = mg
so
gm = (GmM)/r2
mass cancels
g = (GM)/r2
The mass of an object is directly proportional to its gravitational pull. Therefore, the larger the mass of the Earth, the stronger its gravitational pull on the sun.
Yes, the distance between two objects affects the strength of their gravitational pull. The further apart the objects are, the weaker the gravitational pull between them.
Gravity is what keeps the Earth in orbit around the sun. The gravitational force between the two objects is constantly pulling the Earth towards the sun, but the Earth's tangential velocity keeps it in a stable orbit.
The sun does experience a gravitational pull from the Earth, but it is much smaller compared to the sun's own mass. The sun's immense mass and size make it the dominant gravitational force in the solar system.
Yes, the gravitational pull between the Earth and sun can change if there is a change in the mass or distance of either object. However, these changes are very small and do not significantly affect the overall orbit of the Earth around the sun.
