Question

what is the need of gravitational force ?
​

Answer 1

The gravitational force is very important to keep the universe functioning. The planets revolve around the Sun because of the force of gravity Galaxies exist also due to gravitational force. It is the force of gravity that starts the nuclear fusion in stars. Stars exist due to gravitational force.

$<font color= "green">$✧ What is the Gravitational Force?

$<font color= "red">$✒The universe has a lot of forces, a lot of pushes and pulls. We're always pushing or pulling something, even if only the ground. But it turns out that in physics, there are really only four fundamental forces from which everything else is derived: the strong force, the weak force, the electromagnetic force, and the gravitational force.

$<font color= "black">$☞︎︎︎In the equation:

$<font color= "Magenta">$F is the force of gravity (measured in Newtons, N)

G is the gravitational constant of the universe and is always the same number

M is the mass of one object (measured in kilograms, kg)

m is the mass of the other object (measured in kilograms, kg)

r is the distance those objects are apart (measured in meters, m)

So if you know how massive two objects are and how far they are apart, you can figure out the force between them.
