Question

what is gravitational force?​

Answer 1

☃️$\: \: \huge\textbf{\textsf{\color{magenta}{Answer}}} \:$☃️

$\:$

❖ Definition :

The attractive force between any two massive objects is called gravitational force.

$\:$

❖ Examples :

➤ It is our common experience that if a pen slips off from our hands it falls down to the floor.

$\:$

➤ Generally our answer would be that the table supports the pen. If the table does not supports the pen it would fall down until it is supported by another object, like the floor.

$\:$

To get more information :

If an object is thrown upwards, there exists a force which pulls it down towards the earth, because of this it falls down to the ground. We call this force as a gravitational force.

$\:$

Every object on the Earth or close to Earth, will experience a gravitational pull. The force of gravity is not just due to the attraction of the Earth. It is a force of attraction that exists between any two bodies (or masses) everywhere in the universe.

$\:$

As the earth is so massive and huge, all the other objects close to the earth are attracted or pulled towards it. When you sit in your class room, there will be a gravitational force between you and your teacher, and a similar force exists between you and the black board.

$\:$

You cannot experience the gravitational force that exists between you and your teacher or between you and the block board because it is very small when compared to the gravitational force exerted by the earth on these objects.

$\:$

Gravitational force works even the objects are not in contact. So, this is an example of field force.

Answer 2

Answer:

Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are attracted to one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the tides of the oceans.
