## What is the other name of gravitational force?

The most common other name used for gravitational force is **simply gravity**.

## What is a force of attraction or gravity between the object and the Earth?

**Gravity** is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.

## On what does the gravitational attraction between two objects depend?

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 do you call the pull of attraction towards the center of the Earth?

**Gravity** is the force that pulls all objects in the universe toward each other. On Earth, gravity pulls all objects “downward” toward the center of the planet.

## Why is G called the universal gravitational constant?

G is called universal constant **becuase its value remains the same throughout the universe and is independent of masses of the objects**. Answer: Capital G will be constant become the value of the G will be constant anywhere in the Universe.

## What is value of G and G at the Centre of Earth?

That is to say, the acceleration of gravity on the surface of the earth at sea level is **9.8 m/s ^{2}**.

…

The Value of g Depends on Location.

Location | Distance from Earth’s center (m) | Value of g (m/s^{2}) |
---|---|---|

Earth’s surface | 6.38 x 10^{6} m |
9.8 |

1000 km above surface | 7.38 x 10^{6} m |
7.33 |
