Understanding Newton's Law of Universal Gravitation

What does the term 'universal' imply in Newton's law of gravitation?

• It applies only to objects in motion.

• It applies only to celestial bodies.

• It applies to all objects with mass everywhere.

• It applies only to objects on Earth.

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

• The force is halved.

• The force remains the same.

• The force is quadrupled.

• The force is doubled.

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

• The force is tripled.

• The force is reduced to one-third.

• The force is reduced to one-ninth.

• The force remains unchanged.

In the equation F = G * (M1 * M2) / R^2, what does 'G' represent?

• The gravitational force.

• The distance between the objects.

• The gravitational constant.

• The mass of the first object.

If both masses are doubled and the distance is also doubled, what happens to the gravitational force?

• The force is quadrupled.

• The force is halved.

• The force remains the same.

• The force is doubled.

How does the gravitational force change if the separation between two objects is halved?

• The force is doubled.

• The force is quadrupled.

• The force is halved.

• The force remains the same.

What is the effect on gravitational force if the mass of both objects is tripled?

• The force remains unchanged.

• The force is increased nine times.

• The force is reduced to one-third.

• The force is tripled.
