Question

what is the mutual force of all the star, planets and heavenly bodies called?
​

Answer 1

Law of universal gravitation

Answer 2

The mutual force of all stars, planets and heavenly bodies is called gravitational force.

• By Newton's law of universal gravitation:

Gravitational Force F = Gm₁m₂/ r²

Where m₁ and m₂ are the masses of the two objects,

G is the gravitational constant

And r is the distance between the two objects.

• All the bodies in the universe including the stars, planets and heavenly bodies posses this gravitational force of attraction towards other bodies.
