Answer:
Gravitational force increases as the mass of objects increases.
The theory applies to all objects in the universe
Gravitational force increases as the distance between objects decreases.
Explanation:
Newton's theory of universal gravitation states that every object with mass exerts a gravitational force on every other object with mass.
This force is always attractive in nature, and the magnitude of the force is given by:
where
G is the gravitational cosntant
m1, m2 are the two masses
r is the separation between the two masses
We see that the gravitational force is directly proportional to the product of the masses and inversely proportional to the square of their distance.
Therefore, the following statements are correct:
Gravitational force increases as the mass of objects increases.
The theory applies to all objects in the universe
Gravitational force increases as the distance between objects decreases.
While the others are wrong:
The theory applies only to objects on Earth. --> false, the theory applies on every object
Gravitational force increases as mass of objects decreases --> false, the force decreases as the masses decrease
Gravitational force increases as the distance between objects increases --> false, the force decreases as the distance increases
