Understanding Newton's Law of Gravitation

What does Newton's law of gravitation state about the force between two bodies?

• It is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

• It is inversely proportional to the gravitational constant.

• It is inversely proportional to the product of their masses.

• It is directly proportional to the distance between them.

Which other force follows an inverse square law similar to gravity?

• Magnetic force

• Nuclear force

• Electric force

• Frictional force

How does increasing the mass of one of the bodies affect the gravitational force between them?

• The force decreases.

• The force remains the same.

• The force becomes zero.

• The force increases.

What happens to the gravitational force if the distance between two bodies is doubled?

• The force becomes twice as strong.

• The force becomes four times stronger.

• The force becomes four times weaker.

• The force remains unchanged.

If the distance between two bodies is tripled, by what factor does the gravitational force change?

• It becomes three times weaker.

• It becomes nine times weaker.

• It becomes three times stronger.

• It becomes nine times stronger.
