Where does gravity act?

Answer 1

As we all know light is an electromagnetic wave, which is a wave composed of both a magnetic wave and an electric wave. It is also viewed as a particle called a photon. As a light beam approaches the sun it is attracted and repelled by the protons and electrons in the sun. The sum total effect of this, "Gravity" attracts and repels the sun at the same time. Coupled with the speed at which the photon is traveling the beam of light bends around the sun. As the light approaches, the photon is both repelled and attracted at the same time. Its velocity wants to carry it straight on, but as it gets closer to the sun the repulsion begins to effect the photons trajectory. Since the attractive force is greater this will lead to a shorter and sharper bend on the approaching side of the sun and a more gradual slope on the backside of the sun as the particle moves away from the sun. In reality, a constant stream of particles of photons are affected creating an unbroken beam of light that bends around the sun and reaches earth. This is how we are able to view light from a distant star that is hidden by the sun. The influence of matter in the sun on a beam of light as it approaches is what causes the electromagnetic wave to bend around the sun and reach earth.

Answer 2

The gravitational force acts on all bodies with mass at any distance apart. Hence, every object in the universe is gravitationally attracted to every other object. Usually, however, either the object is not massive enough or the distance is too great for the force to have any appreciable effect.

Answer 3

Two objects that have mass will attract each other due to gravitational attraction if they are placed sufficiently close to each other. This is the law of nature. According to Newton's law of universal gravity, this force F is given by:

F = GM1M2/r2

where

G is the gravitational constant

M1 and M2 are the masses of the two bodies

r is the distance between the two bodies

Answer 4

It uses magnetic forces to pull on itself, pulling anything on top of it.

Another opinion:

Gravity has no connection or relationship whatsoever with magnetic force. You'd

have to say that gravity is a property of space that causes a pair of forces that

attract every pair of masses toward each other. It acts on Earth exactly the same

as it behaves everywhere else in the universe.

Answer 5

According to the General Theory Of Relativity the mass of an obgect curves spacetime, the more mass the more the object's gravitational pull.

Answer 6

The gravitational force acts between all objects with mass.

The distance between them is irrelevant.

Answer 7

Gravity acts everywhere not just earth

Answer 8

Because time and mass exist.
