Understanding Newton's Law of Universal Gravitation Quiz

What does Newton's Law of Universal Gravitation state about the force between two objects?

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

If the mass of one object is doubled, how does this affect the gravitational force between two objects?

• It remains the same.
• It doubles.
• It triples.
• It halves.

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

• It increases by a factor of 3.
• It decreases by a factor of 9.
• It remains unchanged.
• It decreases by a factor of 3.

Which of the following scenarios would weaken the gravitational force acting on a planet?

• Increasing the mass of the planet.
• Decreasing the distance to its parent star.
• Decreasing the mass of the planet.
• Increasing the mass of a nearby celestial body.

If a nearby celestial body increases its mass, what effect does this have on the gravitational force experienced by another planet?

• It weakens the force.
• It strengthens the force.
• It has no effect.
• It depends on the distance.

According to the inverse square law, how does the gravitational force change as the distance increases?

• It increases linearly.
• It decreases exponentially.
• It decreases with the square of the distance.
• It remains constant.

What is the gravitational constant (G) value used in calculations?

• 6.674 x 10^11 Nm²/kg²
• 6.674 x 10^-11 Nm²/kg²
• 9.81 m/s²
• 3.14

If a planet moves farther away from its parent star, what is the expected effect on the gravitational force?

• It will increase.
• It will decrease.
• It will remain the same.
• It will fluctuate.

Which of the following best describes the relationship between mass and gravitational force?

• More mass means less gravitational force.
• More mass means more gravitational force.
• Mass has no effect on gravitational force.
• Gravitational force is only dependent on distance.

In the equation F = G(m₁m₂/r²), what does 'r' represent?

• The gravitational force.
• The distance between the centers of the two masses.
• The mass of the first object.
• The mass of the second object.
