Understanding Gravity Quiz

What happens to the force of gravity between two objects if the mass of one object increases?

• The force of gravity between them decreases.

• The force of gravity between them stays the same.

• The force of gravity between them increases.

• The force of gravity between them becomes zero.

According to Newton's law of universal gravitation, what happens to the gravitational force between two objects if the distance between them is doubled?

• The gravitational force becomes twice as strong.

• The gravitational force becomes four times weaker.

• The gravitational force remains unchanged.

• The gravitational force becomes four times stronger.

Which unit is used to measure gravitational force?

• Kilograms (kg)

• Newtons (N)

• Joules (J)

What factor does NOT affect the gravitational force between two objects?

• The mass of the first object

• The mass of the second object

• The color of the objects

• The distance between the two objects

What is gravitational acceleration?

• The acceleration of an object due to the Earth's magnetism

• The acceleration of an object in free fall, solely due to gravity

• The acceleration of an object when it is thrown upwards

• The acceleration of an object moving in a straight line

What is the approximate value of Earth's gravitational acceleration?

Why do astronauts feel weightless in space?

• Because there is no gravity in space.

• Because the gravitational force is much weaker in space.

• Because they are in a continuous state of free fall around the Earth.

• Because their mass decreases in space.

What would happen to your weight if you were on a planet with stronger gravity than Earth's?

• It would decrease.

• It would stay the same.

• It would increase.

• It would fluctuate.

If the distance between two objects is halved, how does the gravitational force between them change?

• It becomes half as strong.

• It becomes twice as strong.

• It becomes four times as strong.

• It does not change.

Which of the following best describes the effect of gravity on light?

• Gravity does not affect light because light has no mass.

• Gravity can bend light.

• Gravity makes light move faster.

• Gravity changes the color of light.
