Question

According to the law of universal gravitation, as mass increases, gravity 1.__________ . As distance increases, gravity 2.________ .

1.
A. Increases
B. Stays the same
C. Decreases

2.
A. Increases
B. Stays the same
C. Decreases

Answer 1

Answer 1

Option A - Increases

Step-by-step explanation

According to the law of universal gravitation, everybody in this universe attracts every other body with a force which is directly proportional to their masses. So, according to this law, when the mass of an object increases its gravity also increases. It shows that mass and gravitational force or gravity has a direct relationship with each other. So if the mass of both the objects is doubled, the force of gravitation between them is quadrupled.

Answer 2

Option C - Decreases.

Step-by-step explanation

According to the law of universal gravitation, everybody in this universe attracts every other body with a force which is inversely proportional to the square of the distance between them. In this way, more the separation between the bodies, weaker will be the gravitational force between the interacting bodies. If the distance between the interacting bodies is doubled, gravity is decreased by four times.

Answer 2

Answer : (1) The correct option is, (A) increases

(2) The correct option is, (C) Decreases

Explanation :

Gravitational force : It is defined as the gravitational force is directly proportional to the product of the masses of the two object and an inversely proportional to the square of the distance between the two object.

`F=G(Mm)/(r^2)`

where,

F = gravitational force or gravity

M and m = mass of two object

r = distance between the two object

G = gravitational constant

When the mass of an object increases then the gravitational force or gravity is increases because gravitational force is directly proportional to the mass of an object.

When the distance between the two object increases then the gravitational force or gravity is decreases because gravitational force is inversely proportional to the distance between the two object.

Hence, (1) As mass increases, gravity increases. (2) As distance increases, gravity decreases.
