Understanding Newton's Universal Law of Gravitation

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

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

• It is directly proportional to the square of the distance between them.

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

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

How does the gravitational force change if the mass of one object is doubled?

• The force quadruples.

• The force halves.

• The force doubles.

• The force remains the same.

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

• The force doubles.

• The force remains the same.

• The force decreases by a factor of 4.

• The force increases by a factor of 4.

Where is the center of mass located in a spherical object with uniform density?

• At the surface of the object.

• Outside the object.

• At the geometrical center of the object.

• At the bottom of the object.

• Isaac Newton

• Albert Einstein

• Henry Cavendish

• Galileo Galilei
