1. Define : gravitation, gravity and gravitational force.
2.
State the universal law of gravitation and its mathematical form.
3.
In what source is 'G' universal?
4. What happens to the force of attraction between two objects when
(i) Their mass are halved?
(ii) Distance between them is increased to 4 times its previous value.
(iii) Distance between them as well as each of the mass is increase to 4 times,
If the distance between two bodies is increased 4 times by what factor should the mass of the bodies be altered so that
the gravitational force between them remains the same?

Answers
Answer:
1.a force of attraction between two object is called gravitation force.
a force that keep us attach with earth,planet around sun is called gravity.
2.gravitation between two object =G* m1*m2/(R)^2
where
G-Gravitational constant
m1-mass of first object
m2-mass of second object
R-distance between two object
Explanation:
3.G represented the universal gravitational constant .

Answer:
1)Gravity, also called gravitation, is a force that exists among all material objects in the universe. For any two objects or particles having nonzero mass, the force of gravity tends to attract them toward each other. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies.
2)The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. In equation form, this is F=GmMr2 F = G mM r 2 , where F is the magnitude of the gravitational force. ... Newton's law of gravitation applies universally.
3)G is known as universal constant because it is equal through out the universe. Its value doesn't change . That is the force of gravitation is directly proportional to the masses of two bodies and inversely proportional to the square of distance between them
