what is the reason for the acceleration due to gravity in planets?

Question

someone says that gravitons are present in the planets, but how they present in the planets .what is the reason?

Answer 1

the constant influence of gravity(force) on an object. when a force is being applied to an object, the object's velocity undergoes a change, hence acceleration. gravity as warped space, think of it as a dip in the road. as a vehicle nears the dip, it accelerates.

Answer 2

Gravity is a force of nature along with electromagnetism,weak and strong nuclear forces (some of these, or all may be just one force in different manifestations). Yo may describe the force between two bodies as being due to an exchange of virtual particles, in which case the graviton would be the exchanging particle for gravity, just as the photon is for the electromagnetic or you may just think of a gravitational field.
Physics describes how and does not give reasons, that's philosophy.

Answer 3

According to newton,gravity is a force but for einstein gravity is due to warping of space-time..in any case matter will be attracted and this is a property of mass...and no gravitions are discovered yet...

Answer 4

Anything that has mass produces gravitons. In other words, anything with mass produces a gravitational field.

Answer 5

When a mass is present in space-time, it distorts it so that whilst it remains true that travelling through space causes you to travel through time, travelling through time now causes you to move (accelerate) through space. In other words just by existing, you are compelled to move through space - this is gravity. All masses, great and small exert their own gravitational force on every other mass, and this force is proportional to their mass.

Answer 6

The Earth's speed around the sun is not precise enough to permit a perfectly circular orbit,

Answer 7

Mass attracts mass.

Answer 8

the curveture of space.
