What is the cause of gravity on earth?

Answer 1

By Newton's law,every two or more bodies have a force acting between them proportional to their masses and inversely proportional to the distance between them.When earth is considered one object and any other object(eg.ball,stone etc.) as the other. There two objects are bodies with finite masses and finite distances between them,they exert a force.But these bodies are neutral in charge and so they always attract each other.Had these bodies been like charged they would repel each other.As the above stated Newton's law is NOT for CHARGED bodies.Thus the body is attracted towards earth. Thus a ball thrown up falls down since the force of attraction between the ball and earth brings it down. And thus gravity exists on earth.

Answer 2

The "cause" of gravity (whatever that means) does not change if gravitons are found to be actual particles. It simply means that gravity is carried by particles in the same way that the other three forces in our Universe. If, somehow and at some time in the future, gravitons are shown to be a derivable result of a "Theory of Everything," then it is extremely unlikely that their existence would make any difference in the nature of gravity, as gravity seems to conform to general relativity to an EXTREMELY close degree. Thus, the existence of gravitons would not change anything about our understanding of gravity.

Indeed, the test of a theoretical framework isn't, "Does your framework show gravitons to exist and gravity to be different from what we think it to be?", it's more like, "Does your framework show gravity to be exactly what we know it to be, even with the presence of gravitons?"

Answer 3

gravity is responsible for the turning of the planet, our ability to keep our feet on the ground, and POSSIBLY our ozone layer.....

Answer 4

The earth's dense core causes the gravity everything on earth experiences

Answer 5

Mass.
