Any object having some mass will attract another object having mass. this is because of gravity. When two objects ahving some mass are separated by some distance then force of gravity acts between them and tends to keep them close that means it is always attractive in nature.

## Why does gravity exist why is any body able to attract another?

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

## Does every body attract each other?

According to Newton’s law of gravitation everybody in this universe attracts every other body. But we do not see bodies on the surface of the earth moving towards one another on account of this interaction. Why? In this equation G = 6.67×10^{–}^{11} Nm^{2}/kg^{2}.

## How does the force of attraction between two bodies?

Gravitational force is directly proportional to the product of the masses of two bodies and inversely proportional to the square of the distance between them. Bodies were thrown from the same height fall at the same speed irrespective of their mass. This is due to acceleration due to gravity.

## Why do two bodies not attract each other?

Well, according to the gravitational law every two objects attract each other with a force and the force is directly proportional to product of their masses and inversely proportional to the square of the distance between them. Except two people in love well it seems NO two objects attract each other.

## Why does matter attract itself?

The tiny particles that make up matter, such as atoms and subatomic particles, also exert forces on one another. These forces are not gravity, but special forces that only these particles use. … These forces can cause one particle to attract, repel, or even destroy another particle.

## Why does gravity exist?

The answer is gravity: an invisible force that pulls objects toward each other. … So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.

## What is difference between G and G?

g is the gravitational force exerted by any planet. For earth it’s 9.8m/s2.

Acceleration due to gravity ( g ) | Universal Gravitation Constant ( G ) |
---|---|

It will change from place to place. | Constant at any place in the universe. |

Value of g=9.8 m/s^{2} |
Value of G=6.673×10-11 Nm^{2}/kg^{2} |

## Do all objects in the universe repel each other?

The law of universal gravitation states that any two objects in the universe, without exception, a. attract each other.

## Why does every object in the universe attracts every other object?

According to Newton every object in the universe attract every other objects with a certain force with which two objects attract each other is called gravitational force. The gravitational force between two objects acts even if the two objects are not connected by any means .

## Does force of attraction between two bodies depend upon the presence of other bodies and properties of intervening medium?

The gravitational force of attraction between the two bodies is independent of presence of other bodies and properties of the intervening medium.

## What is the value of G on Jupiter?

Calculating g on Other Planets

Planet | Radius (m) | g (m/s^{2}) |
---|---|---|

Mercury | 2.43 x 10^{6} |
3.61 |

Venus | 6.073 x 10^{6} |
8.83 |

Mars | 3.38 x 10^{6} |
3.75 |

Jupiter | 6.98 x 10^{7} |
26.0 |

## How does the gravitational force of attraction between two objects depend upon their distance?

The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.

## What is V U GT?

Under gravity, acceleration is 9.8 m/s² and is denoted by g. When an object is falling freely under gravity, then the above equations would be adjusted as follows: v = u + gt. h = ut + 1/2 gt.

## Why the moon does not fall on earth?

The reason is that the Moon is never still. It constantly moves around us. Without the force of gravity from the Earth, it would just float away into space. This mix of velocity and distance from the Earth allows the Moon to always be in balance between fall and escape.

## Which is greater the attraction of earth for 1kg of iron?

The attracting of 1 kg of Iron towards earth is greater. This is all because the Gravitational pull applied by 1 Kg of Iron on Earth is much more times smaller than that of Earth. That much smaller that you can’t even imagine! So, earth possess a larger gravitational pull on 1 Kg of Iron.
